Tony Lindgren 6fa1a9863c ARM: OMAP2+: Drop legacy platform data for dra7 DSS
We can now probe devices with ti-sysc interconnect driver and dts
data. Let's drop the related platform data and custom ti,hwmods
dts property.

As we're just dropping data, and the early platform data init
is based on the custom ti,hwmods property, we want to drop both
the platform data and ti,hwmods property in a single patch.

The OMAP4 DSP hwmod is used in DT, but the DT node is not

Drop the legacy hwmod data for the DSP device along with the

Dave Gerlach 65880ab160 ARM: OMAP2+: pm33xx-core: Extend platform_data ops for cpuidle
In order for am335x and am437x to properly enter deeper c-states in
cpuidle they must always call into the sleep33/43xx suspend code and
also sometimes invoke the wkup_m3_ipc driver. These are both controlled
by the pm33xx module so we must provide a method for the platform code
to call back into the module when it is available as the core cpuidle
ops that are invoked by the cpuidle-arm driver must remain as built in.

Extend the init platform op to take an idle function as an argument so
that we can use this to call into the pm33xx module for c-states that
need it. Also add a deinit op so we can unregister this idle function
from the PM core when the pm33xx module gets unloaded.

Dave Gerlach 06ee7a950b ARM: OMAP2+: pm33xx-core: Add cpuidle_ops for am335x/am437x
am335x and am437x can now make use of the generic cpuidle-arm driver.
This requires that we define init and suspend ops to be passed set as
the cpuidle ops for the SoC. These ops are invoked directly at the last
stage of the cpuidle-arm driver in order to allow low level platform
code to run and bring the CPU the rest of the way into it's desired idle
state. It is required that the CPUIDLE_METHOD_OF_DECLARE be called from
code that is built in so define these ops in pm33xx-core where the
always built-in portion of the PM code for these SoCs lives.

Additionally, although an soc_suspend function is already exposed by the
pm33xx platform code, it contains additional operations needed for full
SoC suspend beyond what is needed for a relatively simple CPU suspend
needed during cpuidle. To get around this introduce cpu_suspend ops to
be used by the am335x and am437x PM driver for the last stage of cpuidle
path.

Tony Lindgren 51c22d7b40 ARM: OMAP2+: Fix compile if CONFIG_HAVE_ARM_SMCCC is not set
Recent omap changes added runtime checks to use omap_smccc_smc()
when optee is configured in dts. As the omap-secure code can be
built for ARMv6 only without ARMv7 and use custom smc calls, we
now get a build error:

omap-secure.c:(.text+0x94): undefined reference to `__arm_smccc_smc'

As there secure calls are not used for ARMv6, we should not build
secure-common, and not call omap_secure_init() for omap2.

Tony Lindgren feaa8baee8 bus: ti-sysc: Implement SoC revision handling
We need to know SoC type and features for cases where the same SoC
may be installed in various versions on the same board and would need
a separate dts file otherwise for the different variants.

For example, am3703 is pin compatible with omap3630, but has sgx and
iva accelerators disabled. We must not try to access the sgx or iva
module registers on am3703, and need to set the unavailable devices
disabled early.

Let's also detect omap3430 as that is needed for display subsystem
(DSS) reset later on, and GP vs EMU or HS devices. Further SoC
specific disabled device detection can be added as needed, such as
dra71x vs dra76x rtc and usb4.

Tony Lindgren f4a5ac7bd9 ARM: OMAP2+: Improve handling of ti-sysc related sysc_fields
We can currently get a cryptic warning sysc_fields (ptrval) != (ptrval)
if the legacy platform data has no sysc_fields defined while the newer
dts data has them. This warning appears only when booting still with
legacy "ti,hwmods" custom property set. This can happen at least with
DSS related modules where we may not have sysc_fields defined in the
in the legacy data.

Let's not error out on missing legacy data sysc_fields, and show a more
descriptive warning for other cases.

Benoit Parrot 2baee0c5b3 ARM: OMAP: DRA7xx: Make CAM clock domain SWSUP only
Both CAL and VIP rely on this clock domain. But CAL DPHY require
LVDSRX_96M_GFCLK to be active. When this domain is set to HWSUP the
LVDSRX_96M_GFCLK is on;y active when VIP1 clock is also active.  If only
CAL on DRA72x (which uses the VIP2 clkctrl) probes the CAM domain is
enabled but the LVDSRX_96M_GFCLK is left gated. Since LVDSRX_96M_GFCLK
is sourcing the input clock to the DPHY then actual frame capture cannot
start as the phy are inactive.

So we either have to also enabled VIP1 even if we don't intend on using
it or we need to set the CAM domain to use SWSUP only.

This patch implements the latter.

Suman Anna 4601832f40 ARM: OMAP2+: use separate IOMMU pdata to fix DRA7 IPU1 boot
The IPU1 MMU has been using common IOMMU pdata quirks defined and
used by all IPU IOMMU devices on OMAP4 and beyond. Separate out the
pdata for IPU1 MMU with the additional .set_pwrdm_constraint ops
plugged in, so that the IPU1 power domain can be restricted to ON
state during the boot and active period of the IPU1 remote processor.
This eliminates the pre-conditions for the IPU1 boot issue as
described in commit afe518400bdb ("iommu/omap: fix boot issue on
remoteprocs with AMMU/Unicache").

NOTE:
1. RET is not a valid target power domain state on DRA7 platforms,
   and IPU power domain is normally programmed for OFF. The IPU1
   still fails to boot though, and an unclearable l3_noc error is
   thrown currently on 4.14 kernel without this fix. This behavior
   is slightly different from previous 4.9 LTS kernel.
2. The fix is currently applied only to IPU1 on DRA7xx SoC, as the
   other affected processors on OMAP4/OMAP5/DRA7 are in domains
   that are not entering RET. IPU2 on DRA7 is in CORE power domain
   which is only programmed for ON power state. The fix can be easily
   scaled if these domains do hit RET in the future.
3. The issue was not seen on current DRA7 platforms if any of the
   DSP remote processors were booted and using one of the GPTimers
   5, 6, 7 or 8 on previous 4.9 LTS kernel. This was due to the
   errata fix for i874 implemented in commit 1cbabcb980 ("ARM:
   DRA7: clockdomain: Implement timer workaround for errata i874")
   which keeps the IPU1 power domain from entering RET when the
   timers are active. But the timer workaround did not make any
   difference on 4.14 kernel, and an l3_noc error was seen still
   without this fix.

Suman Anna 2f14101a1d ARM: OMAP2+: Add workaround for DRA7 DSP MStandby errata i879
Errata Title:
i879: DSP MStandby requires CD_EMU in SW_WKUP

Description:
The DSP requires the internal emulation clock to be actively toggling
in order to successfully enter a low power mode via execution of the
IDLE instruction and PRCM MStandby/Idle handshake. This assumes that
other prerequisites and software sequence are followed.

Workaround:
The emulation clock to the DSP is free-running anytime CCS is connected
via JTAG debugger to the DSP subsystem or when the CD_EMU clock domain
is set in SW_WKUP mode. The CD_EMU domain can be set in SW_WKUP mode
via the CM_EMU_CLKSTCTRL [1:0]CLKTRCTRL field.

Implementation:
This patch implements this workaround by denying the HW_AUTO mode
for the EMU clockdomain during the power-up of any DSP processor
and re-enabling the HW_AUTO mode during the shutdown of the last
DSP processor (actually done during the enabling and disabling of
the respective DSP MDMA MMUs). Reference counting has to be used to
manage the independent sequencing between the multiple DSP processors.

This switching is done at runtime rather than a static clockdomain
flags value to meet the target power domain state for the EMU power
domain during suspend.

Note that the DSP MStandby behavior is not consistent across all
boards prior to this fix. Please see commit 45f871eec6c0 ("ARM:
OMAP2+: Extend DRA7 IPU1 MMU pdata quirks to DSP MDMA MMUs") for
details.

We can now probe devices with ti-sysc interconnect driver and dts
data. Let's drop the related platform data and custom ti,hwmods
dts property.

As we're just dropping data, and the early platform data init
is based on the custom ti,hwmods property, we want to drop both
the platform data and ti,hwmods property in a single patch.

Tony Lindgren 4c74ecf792 dmaengine: ti: omap-dma: Add device tree match data and use it for cpu_pm
With old DMA code disabled for handling DMA requests for device tree based
SoCs, we can move omap3 specific context save and restore to the dmaengine
driver.

Let's do this by adding cpu_pm notifier handling to save and restore context,
and enable it based on device tree match data. This way we can use the match
data later to configure more SoC specific features later on too.

Note that we only clear the channels in use while the platform code also
clears reserved channels 0 and 1 on high-security SoCs. Based on testing
on n900, this is not needed though and the system idles just fine.

With the dmaengine driver handling context save and restore, we must now
remove the old custom calls for context save and restore.

Tony Lindgren 755cbfd8cf ARM: OMAP2+: Drop sdma interrupt handling for mach-omap2
All device tree probing omap SoCs only have device drivers that are using
Linux dmaengine API with the IRQENABLE_L1 interrupts. Only omap1 is still
using old legacy dma.

This means we can remove the legacy sdma interrupt handling for
IRQENABLE_L0, and only rely on the dmaengine driver using IRQENABLE_L1.

The legacy code still allocates the channels, but that will be deal with
in the following patches.

As described in AM437x TRM, spruhl7h, Revised January 2018, there is
an LCDC clockdomain present in the PER power domain. Although it is
entirely unused on AM437x, it should be defined along with the other
clockdomains so it can be shut off by Linux as there are no users.

 - We want to drop the useless gptimer option for omap4 as there are local

 - A minor error path handling improvment for sysc_child_add_named_clock()

With a wl1251 child node of mmc3 in the device tree decoded
in omap_hsmmc.c to handle special wl1251 initialization, we do
no longer need to instantiate the mmc3 through pdata quirks.

We also can remove the wlan regulator and reset/interrupt definitions
and do them through device tree.

This partly reverts the commit efdfeb079c ("regulator: fixed: Convert to
use GPIO descriptor only").

We must remove this from mainline first, so that the following patch
to remove the openpandora quirks for mmc3 and wl1251 cleanly applies
to stable v4.9, v4.14, v4.19 where the above mentioned patch is not yet
present.

Since the code affected is removed (no pandora gpios in pdata-quirks
and more), there will be no matching revert-of-the-revert.

Tony Lindgren 37238d3dd5 ARM: OMAP2+: Drop useless gptimer option for omap4
We have local timers on Cortex-A9, so using the gptimer option makes no
sense. Let's just drop it for omap4 to simplify the timer options a bit.

If this is really needed, it can be still done by specifying dts properties
in the board specific file for assigned-clocks and assigned-clock-parents.

This gets us a bit closer to start dropping legacy platform data for
gptimers except for timer1 that is used for system clockevent.

PRM reset control dts changes for v5.5 merge window

This series of changes adds the PRM reset driver nodes for am3/4, omap4/5
and dra7 SoCs. The reset driver changes make it easier to add support for
various accelerators for TI SoCs in a more generic way.

Note that this branch is based on the PRM reset driver changes branch.

This series of changes continues dropping legacy platform data for
 omaps. With the proper device tree configuration in place in the dts
 files for ti-sysc interconnect target module driver, we can drop the
 related platform data and legacy ti,hwmods custom property.
 
 Most of the patches in this series drop platform data and custom dts
 property one device class and one SoC at time. This way we can easily
 revert one patch at a time in case of unexpected issues if the fix is
 not trivial.
 
 For am335x musb, we need to first update the device tree to probe with
 ti-sysc interconnect target module driver. And then the following
 patches drop the legacy platform data.
 
 Note that this series depends on earlier ti-sysc related driver changes

Tony Lindgren c145649bf2 ARM: OMAP2+: Configure voltage controller for cpcap to low-speed
Looks like the i2c timings in high-speed mode do not work properly to
allow us to clear I2C_DISABLE bits for PRM_VOLTCTRL register and the
device reboots if I2C_DISABLE bits are cleared.

Let's configure the voltage controller i2c for low-speed mode as done in
the Motorola Mapphone Android Linux kernel. This saves us about 7mW of
power during retention compared to the high-speed values.

Let's also change the low-speed warning to pr_info about relying on the
bootloader configured low-speed values like we currently do.

The OMAP3 ISP IOMMU does not have any reset lines, so it didn't
need any pdata previously. The OMAP IOMMU driver now requires the
platform data ops for device_enable/idle on all the IOMMU devices
after commit db8918f61d ("iommu/omap: streamline enable/disable
through runtime pm callbacks") to enable/disable the clocks properly
and maintain the reference count and the omap_hwmod state machine.
So, add these callbacks through iommu pdata quirks for the OMAP3
ISP IOMMU.

Tony Lindgren 4873843718 ARM: OMAP2+: Initialize voltage controller for omap4
We're missing initializing the PRM_VOLTCTRL register for voltage
controller. Let's add omap4_vc_init_pmic_signaling() similar to what we
have for omap3 and enable voltage control for retention.

This brings down droid4 power consumption with mainline kernel to somewhere
between 40 and 50mW from about 70 to 80 mW for the whole device when
running idle with LCD and backlight off, WLAN connected, and USB and modem
modules unloaded.

Mostly just rmmod of omap2430, ohci-platform and phy-mapphone-mdm6600 are
needed to idle USB and shut down the modem. And after that measuring idle
power consumption can be done with reading sysfs entry periodically
for /sys/class/power_supply/battery/power_avg. Then rmmod of phy-cpcap-usb
will save few more mW, but will disable the debug UART.

Note that sometimes CM_L4PER_UART1_CLKCTRL at 0x4a009540 does not idle
properly after unloading of phy-mapphone-mdm6600.

Tony Lindgren d44fa156dc ARM: OMAP2+: Configure voltage controller for cpcap
We can configure voltage controller for cpcap with the data available in
Motorola Mapphone Android Linux kernel. Let's add it so we can have droid4
behave the same way for voltage controller as other omap4 devices and save
some power when idle.

Note that we're now using high-speed i2c mode, looks like the Motorola
kernel had a typo using 0x200 instead of 200 for the timings which may
caused it to not work properly.

Also note that in the long run, this should just become dts data for a
voltage controller device driver. But let's get things working first to
make it possible to test further changes easily.

Commit 0ed266d7ae ("clk: ti: omap3: cleanup unnecessary clock aliases")
removed old omap3 clock framework aliases but caused omap3-rom-rng to
stop working with clock not found error.

Based on discussions on the mailing list it was requested by Tero Kristo
that it would be best to fix this issue by probing omap3-rom-rng using
device tree to provide a proper clk property. The other option would be
to add back the missing clock alias, but that does not help moving things
forward with removing old legacy platform_data.

Let's also add a proper device tree binding and keep it together with
the fix.

 - For omap3-gta04, gpio changes caused the LCD to break a while back,
   and after discussing things the right fix is to set spi-cs-high
 
 - Recent omapdrm changes to use generic panels caused tfp410 to be
   disabled as we now must enable the generic support for it in
   defconfig
 
 - Recent omapdrm and backlight changes also finally made droid4 LCD
   to work, so let's enable it in the defconfig it can be used out
   of the box. This is not strictly a fix, but we still also have the
   older CONFIG_MFD_TI_LMU options available so this cuts down the
   confusion for trying to guess which display and which backlight
   is needed
 
 - Recent ti-sysc interconnect target module changes need the gpio
   module disabled on some boards, but this now needs to happen at
   the module level, not at the gpio driver level
 
 - Recent changes to probe system timers with ti-sysc caused warnings
   about mismatch in syconfig registers, so let's configure the option
   for RESET_STATUS as available in the TRMs
 
 - Recent changes to probe LCDC with ti-sysc caused warnings about
   mismatch in sysconfig registers, so let's configure the missing
   idlemodes for both platform data and dts as documented in TRMs
 
 - Since we moved mach-omap2 to probe with device tree, we've been
   getting voltage controller warnings. Turns out this code is no
   longer needed, so let's just remove omap2_set_init_voltage() to
   get rid of the pointless warnings

Tony Lindgren cf395f7ddb ARM: OMAP2+: Fix warnings with broken omap2_set_init_voltage()
This code is currently unable to find the dts opp tables as ti-cpufreq
needs to set them up first based on speed binning.

We stopped initializing the opp tables with platform code years ago for
device tree based booting with commit 92d51856d7 ("ARM: OMAP3+: do not
register non-dt OPP tables for device tree boot"), and all of mach-omap2
is now booting using device tree.

We currently get the following errors on init:

omap2_set_init_voltage: unable to find boot up OPP for vdd_mpu
omap2_set_init_voltage: unable to set vdd_mpu
omap2_set_init_voltage: unable to find boot up OPP for vdd_core
omap2_set_init_voltage: unable to set vdd_core
omap2_set_init_voltage: unable to find boot up OPP for vdd_iva
omap2_set_init_voltage: unable to set vdd_iva

Let's just drop the unused code. Nowadays ti-cpufreq should be used to
to initialize things properly.

standbymode and idlemode that should be just the sidle and midle
registers where midle is currently unconfigured for lcdc_sysc. As
the dts data has been generated based on lcdc_sysc, we now have an
empty "ti,sysc-midle" property.

And so we currently get a warning for lcdc because of a difference
with dts provided configuration compared to the legacy platform
data. This is because lcdc has SYSC_HAS_MIDLEMODE configured in
the platform data without configuring the modes.

Let's fix the issue by adding the missing midlemode to lcdc_sysc,
and configuring the "ti,sysc-midle" property based on the TRM
values.

Tony Lindgren 8ad8041b98 ARM: OMAP2+: Fix missing reset done flag for am3 and am43
For ti,sysc-omap4 compatible devices with no sysstatus register, we do have
reset done status available in the SOFTRESET bit that clears when the reset
is done. This is documented for example in am437x TRM for DMTIMER_TIOCP_CFG
register. The am335x TRM just says that SOFTRESET bit value 1 means reset is
ongoing, but it behaves the same way clearing after reset is done.

With the ti-sysc driver handling this automatically based on no sysstatus
register defined, we see warnings if SYSC_HAS_RESET_STATUS is missing in the
legacy platform data:

ti-sysc 48042000.target-module: sysc_flags 00000222 != 00000022
ti-sysc 48044000.target-module: sysc_flags 00000222 != 00000022
ti-sysc 48046000.target-module: sysc_flags 00000222 != 00000022
...

Let's fix these warnings by adding SYSC_HAS_RESET_STATUS. Let's also
remove the useless parentheses while at it.

If it turns out we do have ti,sysc-omap4 compatible devices without a
working SOFTRESET bit we can set up additional quirk handling for it.

Linus Torvalds f97c81dc6c ARM: SoC: late updates for v5.4
This is some material that we picked up into our tree late or
 that had complex inter-depondencies. The fact that there are these
 interdependencies tends to meant that these are often actually the most
 interesting new additions:
 
 The new Aspeed AST2600 baseboard management controller is added, this
 is a Cortex-A7 based follow-up to the ARM11 based AST2500 and had some
 dependencies on other device drivers.
 
 After many years, support for the MMP2 based OLPC XO-1.75 finally makes
 it into the kernel.
 
 The Armada 3720 based Turris Mox open source router platform is a late
 addition and it follows some preparatory work across multiple branches.
 
 The OMAP2+ platform had some large-scale cleanup involving driver
 changes and DT changes, here we finish it off, dropping a lot of the
 now-unused platform data.
 
 The TI K3 platform that got added for 5.3 gains a lot more support
 for individual bits on the SoC, this part just came late for the
 merge window.

Linus Torvalds 2b97c39514 ARM: SoC platform updates for v5.4
The main change this time around is a cleanup of some of the oldest
 platforms based on the XScale and ARM9 CPU cores, which are between 10
 and 20 years old.
 
 The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel
 IOP33x/IOP13xx platforms are removed after we determined that nobody is
 using them any more.
 
 The TI Davinci and NXP LPC32xx platforms on the other hand are still in
 active use and are converted to the ARCH_MULTIPLATFORM build, meaning
 that we can compile a kernel that works on these along with most other
 ARMv5 platforms. Changes toward that goal are also merged for IOP32x,
 but additional work is needed to complete this. Patches for the
 remaining ARMv5 platforms have started but need more work and some
 testing.
 
 Support for the new ASpeed AST2600 gets added, this is based on the
 Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and
 ARMv6 chips in the same family.
 
 Other changes include a cleanup of the ST-Ericsson ux500 platform
 and the move of the TI Davinci platform to a new clocksource driver.

in device tree we must succeed with clk_get() to continue. For modules with
no clock names specified in device tree we will just ignore the clocks.

Arnd Bergmann feeb04ce91 Drop legacy platform data omap variants for v5.4
We can now drop more platform data in favor of dts data for most
 devices like cpsw, gpio, i2c, mmc, uart and watchdog.
 
 In general we can do this by dropping legacy "ti,hwmods" custom dts
 property, and the platform data assuming the related dts data is correct.
 This is best done as single patch as otherwise we'd have to revert two
 patches in case of any unexpected issues, and we're just removing data.
 
 Fro cpsw, before we can do this, we need to configure the cpsw mdio clocks
 properly in dts though in the first patch. For omap4 i2c, we've already
 dropped the platform data earlier, but have been still allocting it
 dynamically based on the dts data based on the "ti,hwmods" property, but
 that is no longer needed. For d2d, we are missing the dts data, so we
 first add it and then drop the platform data.
 
 For dra7, we drop platform data and "ti,hwmods" for mcasp and mcspi.
 We've already dropped platform data earlier for gpio, i2c, mmc, and
 uart so we just need to drop "ti,hwmods" property for those.
 
 Note that this branch is based on earlier ti-sysc-fixes branch.

Drop legacy platform data omap variants for v5.4

We can now drop more platform data in favor of dts data for most
devices like cpsw, gpio, i2c, mmc, uart and watchdog.

In general we can do this by dropping legacy "ti,hwmods" custom dts
property, and the platform data assuming the related dts data is correct.
This is best done as single patch as otherwise we'd have to revert two
patches in case of any unexpected issues, and we're just removing data.

Fro cpsw, before we can do this, we need to configure the cpsw mdio clocks
properly in dts though in the first patch. For omap4 i2c, we've already
dropped the platform data earlier, but have been still allocting it
dynamically based on the dts data based on the "ti,hwmods" property, but
that is no longer needed. For d2d, we are missing the dts data, so we
first add it and then drop the platform data.

For dra7, we drop platform data and "ti,hwmods" for mcasp and mcspi.
We've already dropped platform data earlier for gpio, i2c, mmc, and
uart so we just need to drop "ti,hwmods" property for those.

Note that this branch is based on earlier ti-sysc-fixes branch.

Masahiro Yamada ccf4975dca ARM: OMAP2+: move platform-specific asm-offset.h to arch/arm/mach-omap2
<generated/ti-pm-asm-offsets.h> is only generated and included by
arch/arm/mach-omap2/, so it does not need to reside in the globally
visible include/generated/.

I renamed it to arch/arm/mach-omap2/pm-asm-offsets.h since the prefix
'ti-' is just redundant in mach-omap2/.

My main motivation of this change is to avoid the race condition for
the parallel build (-j) when CONFIG_IKHEADERS is enabled.

When it is enabled, all the headers under include/ are archived into
kernel/kheaders_data.tar.xz and exposed in the sysfs.

In the parallel build, we have no idea in which order files are built.

 - If ti-pm-asm-offsets.h is built before kheaders_data.tar.xz,
   the header will be included in the archive. Probably nobody will
   use it, but it is harmless except that it will increase the archive
   size needlessly.

 - If kheaders_data.tar.xz is built before ti-pm-asm-offsets.h,
   the header will not be included in the archive. However, in the next
   build, the archive will be re-generated to include the newly-found
   ti-pm-asm-offsets.h. This is not nice from the build system point
   of view.

 - If ti-pm-asm-offsets.h and kheaders_data.tar.xz are built at the
   same time, the corrupted header might be included in the archive,
   which does not look nice either.

This commit fixes the race.

# echo on > $(find /sys -name control | grep \/5601)
# rwmem 0x56000024
0x56000024 = 0x00010200		# SGX540 CORE_REVISION
# echo auto > $(find /sys -name control | grep \/5601)
# rwmem 0x56000024
And when idled, it will produce "Bus error" as expected.

Suman Anna 3846a3b951 iommu/omap: fix boot issue on remoteprocs with AMMU/Unicache
Support has been added to the OMAP IOMMU driver to fix a boot hang
issue on OMAP remoteprocs with AMMU/Unicache, caused by an improper
AMMU/Unicache state upon initial deassertion of the processor reset.
The issue is described in detail in the next three paragraphs.

All the Cortex M3/M4 IPU processor subsystems in OMAP SoCs have a
AMMU/Unicache IP that dictates the memory attributes for addresses
seen by the processor cores. The AMMU/Unicache is configured/enabled
by the SCACHE_CONFIG.BYPASS bit - a value of 1 enables the cache and
mandates all addresses accessed by M3/M4 be defined in the AMMU. This
bit is not programmable from the host processor. The M3/M4 boot
sequence starts out with the AMMU/Unicache in disabled state, and
SYS/BIOS programs the AMMU regions and enables the Unicache during
one of its initial boot steps. This SCACHE_CONFIG.BYPASS bit is
however enabled by default whenever a RET reset is applied to the IP,
irrespective of whether it was previously enabled or not. The AMMU
registers lose their context whenever this reset is applied. The reset
is effective as long as the MMU portion of the subsystem is enabled
and clocked. This behavior is common to all the IPU and DSP subsystems
that have an AMMU/Unicache.

The IPU boot sequence involves enabling and programming the MMU, and
loading the processor and releasing the reset(s) for the processor.
The PM setup code currently sets the target state for most of the
power domains to RET. The L2 MMU can be enabled, programmed and
accessed properly just fine with the domain in hardware supervised
mode, while the power domain goes through a RET->ON->RET transition
during the programming sequence. However, the ON->RET transition
asserts a RET reset, and the SCACHE_CONFIG.BYPASS bit gets auto-set.
An AMMU fault is thrown immediately when the M3/M4 core's reset is
released since the first instruction address itself will not be
defined in any valid AMMU regions. The ON->RET transition happens
automatically on the power domain after enabling the iommu due to
the hardware supervised mode.

This patch adds and invokes the .set_pwrdm_constraint pdata ops, if
present, during the OMAP IOMMU enable and disable functions to resolve
the above boot hang issue. The ops will allow to invoke a mach-omap2
layer API pwrdm_set_next_pwrst() in a multi-arch kernel environment.
The ops also returns the current power domain state while enforcing
the constraint so that the driver can store it and use it to set back
the power domain state while releasing the constraint. The pdata ops
implementation restricts the target power domain to ON during enable,
and back to the original power domain state during disable, and thereby
eliminating the conditions for the boot issue. The implementation is
effective only when the original power domain state is either RET or
OFF, and is a no-op when it is ON or INACTIVE.

The .set_pwrdm_constraint ops need to be plugged in pdata-quirks
for the affected remote processors to be able to boot properly.

Note that the current issue is seen only on kernels with the affected
power domains programmed to enter RET. For eg., IPU1 on DRA7xx is in a
separate domain and is susceptible to this bug, while the IPU2 subsystem
is within CORE power domain, and CORE RET is not supported on this SoC.
IPUs on OMAP4 and OMAP5 are also susceptible since they are in CORE power
domain, and CORE RET is a valid power target on these SoCs.

Here is the "big" driver core and debugfs changes for 5.3-rc1
 
 It's a lot of different patches, all across the tree due to some api
 changes and lots of debugfs cleanups.  Because of this, there is going
 to be some merge issues with your tree at the moment, I'll follow up
 with the expected resolutions to make it easier for you.
 
 Other than the debugfs cleanups, in this set of changes we have:
 	- bus iteration function cleanups (will cause build warnings
 	  with s390 and coresight drivers in your tree)
 	- scripts/get_abi.pl tool to display and parse Documentation/ABI
 	  entries in a simple way
 	- cleanups to Documenatation/ABI/ entries to make them parse
 	  easier due to typos and other minor things
 	- default_attrs use for some ktype users
 	- driver model documentation file conversions to .rst
 	- compressed firmware file loading
 	- deferred probe fixes
 
 All of these have been in linux-next for a while, with a bunch of merge
 issues that Stephen has been patient with me for.  Other than the merge
 issues, functionality is working properly in linux-next :)

Pull driver core and debugfs updates from Greg KH:
 "Here is the "big" driver core and debugfs changes for 5.3-rc1

  It's a lot of different patches, all across the tree due to some api
  changes and lots of debugfs cleanups.

  Other than the debugfs cleanups, in this set of changes we have:

   - bus iteration function cleanups

   - scripts/get_abi.pl tool to display and parse Documentation/ABI
     entries in a simple way

   - cleanups to Documenatation/ABI/ entries to make them parse easier
     due to typos and other minor things

   - default_attrs use for some ktype users

   - driver model documentation file conversions to .rst

   - compressed firmware file loading

   - deferred probe fixes

  All of these have been in linux-next for a while, with a bunch of
  merge issues that Stephen has been patient with me for"

Linus Torvalds fe2da896fd ARM: SoC fixes
A smaller batch of fixes, nothing that stands out as risky or scary.
 
 Mostly DTS tweaks for a few issues:
  - GPU fixlets for Meson
  - CPU idle fix for LS1028A
  - PWM interrupt fixes for i.MX6UL
 
 Also, enable a driver (FSL_EDMA) on arm64 defconfig, and a warning and
 two MAINTAINER tweaks.

Stefan Agner b8ad2985c6 ARM: OMAP2: drop explicit assembler architecture
OMAP2 depends on ARCH_MULTI_V6, which makes sure that the kernel is
compiled with -march=armv6. The compiler frontend will pass the
architecture to the assembler. There is no explicit architecture
specification necessary.

Stefan Agner 3fe1ee40b2 ARM: use arch_extension directive instead of arch argument
The LLVM Target parser currently does not allow to specify the security
extension as part of -march (see also LLVM Bug 40186 [0]). When trying
to use Clang with LLVM's integrated assembler, this leads to build
errors such as this:
  clang-8: error: the clang compiler does not support '-Wa,-march=armv7-a+sec'

Use ".arch_extension sec" to enable the security extension in a more
portable fasion. Also make sure to use ".arch armv7-a" in case a v6/v7
multi-platform kernel is being built.

Note that this is technically not exactly the same as the old code
checked for availabilty of the security extension by calling as-instr.
However, there are already other sites which use ".arch_extension sec"
unconditionally, hence de-facto we need an assembler capable of
".arch_extension sec" already today (arch/arm/mm/proc-v7.S). The
arch extension "sec" is available since binutils 2.21 according to
its documentation [1].

omap3xxx_prm_enable_io_wakeup() is marked __init, but its caller is not, so
we get a warning with clang-8:

WARNING: vmlinux.o(.text+0x343c8): Section mismatch in reference from the function omap3xxx_prm_late_init() to the function .init.text:omap3xxx_prm_enable_io_wakeup()
The function omap3xxx_prm_late_init() references
the function __init omap3xxx_prm_enable_io_wakeup().
This is often because omap3xxx_prm_late_init lacks a __init
annotation or the annotation of omap3xxx_prm_enable_io_wakeup is wrong.

When building with gcc, omap3xxx_prm_enable_io_wakeup() is always
inlined, so we never noticed in the past.

Tony Lindgren 2b2f7def05 bus: ti-sysc: Add support for missing clockdomain handling
We need to let ti-sysc driver manage clockdomain autoidle for the
duration of of reset, enable and idle. And we need to do it before we
enable the clock and after we disable it. Currently we are still
relying on platform callbacks indirectly managing clockdomain autoidle.
But I noticed that for device tree only probed drivers it now happens
only after we enabling the clocks and before we disable the clocks,
while it should be the other way around. So far I have not noticed
any issues with this though.

Let's add new ti_sysc_clkdm_deny_idle() and ti_sysc_clkdm_allow_idle()
functions for ti-sysc driver to use to manage clockdomains directly via
platform data callbacks. Note that we can implement the clockdomain
functions in pdata-quirks.c as for probing devices without "ti,hwmods"
custom property we don't need to use the other platform data callbacks.

Let's do this in one patch as there's is still an unlikely chance we
may need to apply this as a fix for v5.2 for dropping legacy platform
data for some devices. We also do have the option of adding back the
platform data if needed in case of trouble.

Linus Torvalds 22c58fd70c ARM: SoC platform updates
SoC updates, mostly refactorings and cleanups of old legacy platforms.
 Major themes this release:
 
  - Conversion of ixp4xx to a modern platform (drivers, DT, bindings)
  - Moving some of the ep93xx headers around to get it closer to multiplatform enabled.
  - Cleanups of Davinci
 
 This tag also contains a few patches that were queued up as fixes before
 5.1 but I didn't get sent in before release.

Olof Johansson e639861344 Driver changes for ti-sysc for v5.2 merge window
This series of changes for ti-sysc interconnect target module driver
 gets us to the point where we can actually drop legacy platform data
 for many devices in favor of device tree data.
 
 To do this, we improve ti-sysc driver not to rely on platform data
 callbacks to manage module clocks, and handle more quirks needed for
 some devices. Also few minor fixes are needed, but were considered
 not needed to be sent separately as they only show up with this series.
 
 Then we drop several thousands of lines of legacy platform data for
 omap4, omap5, dra7, am335x and am437x. We drop platform data for mmc,
 i2c, gpio and uart devices to start with as those are typically
 easily tested on all devices. In case of unexpected issues, we can just
 add back the legacy platform data for a single device type if needed.
 
 Finally we add initial support for enabling and disabling some devices
 without legacy platform data callbacks. I was planning on sending the
 dropping of legacy platform data as a separate series, but already
 applied Roger's patch on top and pushed it out.
 
 Note that this series depends on related SoC and is based on those.

Dave Gerlach 11140cc40d ARM: OMAP2+: sleep43xx: Run EMIF HW leveling on resume path
When returning from DeepSleep mode on AM437x platforms the EMIF must run
DDR hardware leveling, same as done during u-boot, to properly restore the
EMIF PHY to it's operational state on platforms using DDR3.

Call the ti-emif-sram-pm run_hw_leveling routine to perform this. This
happens after all other EMIF values are restored so the exact same
configuration used at boot is used at the end of EMIF resume as well.

Tony Lindgren b4a9a7a389 bus: ti-sysc: Handle swsup idle mode quirks
In preparation of dropping interconnect target module platform data in
favor of devicetree based data, we must pass swsup idle quirks to the
platform data functions.

For now, let's only tag the UART modules with the SWSUP_SIDLE_ACT quirk.
The other modules will get tagged with swsup quirks as we drop the
platform data and test the changes.

Tony Lindgren b57250fa5e ARM: OMAP2+: Allocate struct omap_hwmod based on dts data
With ti-sysc interconnect target module, we can allocate struct omap_hwmod
data based on the devicetree data. This allows dropping the static SoC
specific data eventually so we will only boot with data we actually need.

To allocate struct omap_hwmod dynamically, we need to add a mutex for
modifying the list, and remove __init for few functions.

Note that we are not initialized oh->_clk or the optional clocks and their
related quirks. That can be directly handled by the interconnect target
module driver.

For dynamically allocated struct hwmod entries probing with ti-sysc

For dynamically allocated sysconfig data we only need to allocate a new
class for the cases where the class is shared. For dynamically allocated
struct omap_hwmod we will always allocate a new class.

Let's add detection for when we need to allocate a new class by comparing
the class name against the module name. If they match, there's no need
to allocate a new calls as we don't have case of mixed platform data and
dts data initialized modules for the same class.

Let's also move the init of class data inside the spinlock.

Tony Lindgren 7f0d078667 ARM: OMAP2+: Fix potentially uninitialized return value for _setup_reset()
Commit 747834ab83 ("ARM: OMAP2+: hwmod: revise hardreset behavior") made
the call to _enable() conditional based on no oh->rst_lines_cnt. This
caused the return value to be potentially uninitialized. Curiously we see
no compiler warnings for this, probably as this gets inlined.

We call _setup_reset() from _setup() and only _setup_postsetup() if the
return value is zero. Currently the return value can be uninitialized for
cases where oh->rst_lines_cnt is set and HWMOD_INIT_NO_RESET is not set.

Linus Torvalds dc2535be1f We have a fairly balanced mix of clk driver updates and clk framework
updates this time around. It's the usual pile of new drivers for new
 hardware out there and the normal small fixes and updates, but then we
 have some core framework changes too.
 
 In the core framework, we introduce support for a clk_get_optional() API
 to get clks that may not always be populated and a way to devm manage clkdev
 lookups registered by provider drivers. We also do some refactoring to simplify
 the interface between clkdev and the common clk framework so we can reuse the DT
 parsing and clk_get() path in provider drivers in the future. This work will
 continue in the next few cycles while we convert how providers specify clk
 parents.
 
 On the driver side, the biggest part of the dirstat is the Amlogic clk driver
 that got support for the G12A SoC. It dominates with almost half the overall
 diff, while the second largest part of the diff is in the i.MX clk driver
 that gained support for imx8mm SoCs. After that, we have the Actions Semiconductor
 and Qualcomm drivers rounding out the big part of the dirstat because they both
 got new hardware support for SoCs. The rest is just various updates and non-critical
 fixes for existing drivers.
 
 Core:
  - Convert a few clk bindings to JSON schema format
  - Add a {devm_}clk_get_optional() API
  - Add devm_clk_hw_register_clkdev() API to manage clkdev lookups
  - Start rewriting clk parent registration and supporting device links
    by moving around code that supports clk_get() and DT parsing of the
    'clocks' property
 
 New Drivers:
  - Add Qualcomm MSM8998 RPM managed clks
  - IPA clk support on Qualcomm RPMh clk controllers
  - Actions Semi S500 SoC clk support
  - Support for fixed rate clks populated from an MMIO register
  - Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car V3H
  - Add TMU (timer) clocks on Renesas RZ/G2E
  - Add Amlogic G12A Always-On Clock Controller
  - Add 32k clock generation for Amlogic AXG
  - Add support for the Mali GPU clocks on Amlogic Meson8
  - Add Amlogic G12A EE clock controller driver
  - Add missing CANFD clocks on Renesas RZ/G2M and RZ/G2E
  - Add i.MX8MM SoC clk driver support
 
 Removed Drivers:
  - Remove clps711x driver as the board support is gone
 
 Updates:
  - 3rd ECO fix for Mediatek MT2712 SoCs
  - Updates for Qualcomm MSM8998 GCC clks
  - Random static analysis fixes for clk drivers
  - Support for sleeping gpios in the clk-gpio type
  - Minor fixes for STM32MP1 clk driver (parents, critical flag, etc.)
  - Split LCDC into two clks on the Marvell MMP2 SoC
  - Various DT of_node refcount fixes
  - Get rid of CLK_IS_BASIC from TI code (yay!)
  - TI Autoidle clk support

Linus Torvalds 6ad63dec9c ARM: SoC device tree updates for 5.1
This is a smaller update than the past few times, but with just over
 500 non-merge changesets still dwarfes the rest of the SoC tree.
 
 Three new SoC platforms get added, each one a follow-up to an existing
 product, and added here in combination with a reference platform:
 
  - Renesas RZ/A2M (R7S9210) 32-bit Cortex-A9 Real-time imaging processor
    https://www.renesas.com/eu/en/products/microcontrollers-microprocessors/rz/rza/rza2m.html
 
  - Renesas RZ/G2E (r8a774c0) 64-bit Cortex-A53 SoC "for
    Rich Graphics Applications".

    Tools GmbH, based on the Texas Instruments AM335x chip
 
  - Winterland IceBoard is a Texas Instruments AM3874 based
    machine used in telescopes at the south pole and elsewhere, see commit
    d031773169 for some pointers:

  - X96 Max, a generic TV box based on Amlogic G12a (S905X2)
 
  - NVIDIA Shield TV (Darcy) based on Tegra210
 
 And then there are several new SBC, evaluation, development or modular
 systems that we add:
 
  - Three new Rockchips rk3399 based boards:
     - FriendlyElec NanoPC-T4 and NanoPi M4
     - Radxa ROCK Pi 4

    system in 96boards form factor
 
  - Arm Fixed Virtual Platforms(FVP) Base RevC, a purely
    virtual platform for corresponding to the latest "fast model"

Andreas Kemnade 12af39cad7 ARM: OMAP2+: hwmod: disable ick autoidling when a hwmod requires that
Deny autoidle for hwmods with the OCPIF_SWSUP_IDLE flag,
that makes hwmods working properly which cannot handle
autoidle properly in lower power states.
Affected is e. g. the omap_hdq.
Since an ick might have mulitple users, autoidle is disabled
when an individual user requires that rather than in
_setup_iclk_autoidle. dss_ick is an example for that.

Russell King 50d6b3cf94 ARM: OMAP2+: fix lack of timer interrupts on CPU1 after hotplug
If we have a kernel configured for periodic timer interrupts, and we
have cpuidle enabled, then we end up with CPU1 losing timer interupts
after a hotplug.

This can manifest itself in RCU stall warnings, or userspace becoming
unresponsive.

The problem is that the kernel initially wants to use the TWD timer
for interrupts, but the TWD loses context when we enter the C3 cpuidle
state.  Nothing reprograms the TWD after idle.

We have solved this in the past by switching to broadcast timer ticks,
and cpuidle44xx switches to that mode at boot time.  However, there is
nothing to switch from periodic mode local timers after a hotplug
operation.

We call tick_broadcast_enter() in omap_enter_idle_coupled(), which one
would expect would take care of the issue, but internally this only
deals with one-shot local timers - tick_broadcast_enable() on the other
hand only deals with periodic local timers.  So, we need to call both.

Linus Walleij 01dc79cd6f
regulator: fixed/gpio: Pull inversion/OD into gpiolib
This pushes the handling of inversion semantics and open drain
settings to the GPIO descriptor and gpiolib. All affected board
files are also augmented.

This is especially nice since we don't have to have any
confusing flags passed around to the left and right littering
the fixed and GPIO regulator drivers and the regulator core.
It is all just very straight-forward: the core asks the GPIO
line to be asserted or deasserted and gpiolib deals with the
rest depending on how the platform is configured: if the line
is active low, it deals with that, if the line is open drain,
it deals with that too.

Russell King 5388a5b821 ARM: avoid Cortex-A9 livelock on tight dmb loops
machine_crash_nonpanic_core() does this:

	while (1)
		cpu_relax();

because the kernel has crashed, and we have no known safe way to deal
with the CPU.  So, we place the CPU into an infinite loop which we
expect it to never exit - at least not until the system as a whole is
reset by some method.

In the absence of erratum 754327, this code assembles to:

	b	.

In other words, an infinite loop.  When erratum 754327 is enabled,
this becomes:

1:	dmb
	b	1b

It has been observed that on some systems (eg, OMAP4) where, if a
crash is triggered, the system tries to kexec into the panic kernel,
but fails after taking the secondary CPU down - placing it into one
of these loops.  This causes the system to livelock, and the most
noticable effect is the system stops after issuing:

	Loading crashdump kernel...

to the system console.

The tested as working solution I came up with was to add wfe() to
these infinite loops thusly:

	while (1) {
		cpu_relax();
		wfe();
	}

which, without 754327 builds to:

1:	wfe
	b	1b

or with 754327 is enabled:

1:	dmb
	wfe
	b	1b

Adding "wfe" does two things depending on the environment we're running
under:
- where we're running on bare metal, and the processor implements
  "wfe", it stops us spinning endlessly in a loop where we're never
  going to do any useful work.
- if we're running in a VM, it allows the CPU to be given back to the
  hypervisor and rescheduled for other purposes (maybe a different VM)
  rather than wasting CPU cycles inside a crashed VM.

However, in light of erratum 794072, Will Deacon wanted to see 10 nops
as well - which is reasonable to cover the case where we have erratum
754327 enabled _and_ we have a processor that doesn't implement the
wfe hint.

So, we now end up with:

1:      wfe
        b       1b

when erratum 754327 is disabled, or:

1:      dmb
        nop
        nop
        nop
        nop
        nop
        nop
        nop
        nop
        nop
        nop
        wfe
        b       1b

when erratum 754327 is enabled.  We also get the dmb + 10 nop
sequence elsewhere in the kernel, in terminating loops.

This is reasonable - it means we get the workaround for erratum
794072 when erratum 754327 is enabled, but still relinquish the dead
processor - either by placing it in a lower power mode when wfe is
implemented as such or by returning it to the hypervisior, or in the
case where wfe is a no-op, we use the workaround specified in erratum
794072 to avoid the problem.

These as two entirely orthogonal problems - the 10 nops addresses
erratum 794072, and the wfe is an optimisation that makes the system
more efficient when crashed either in terms of power consumption or
by allowing the host/other VMs to make use of the CPU.

I don't see any reason not to use kexec() inside a VM - it has the
potential to provide automated recovery from a failure of the VMs
kernel with the opportunity for saving a crashdump of the failure.
A panic() with a reboot timeout won't do that, and reading the
libvirt documentation, setting on_reboot to "preserve" won't either
(the documentation states "The preserve action for an on_reboot event
is treated as a destroy".)  Surely it has to be a good thing to
avoiding having CPUs spinning inside a VM that is doing no useful
work.
