As there is no common panel framework in the kernel, we have OMAP
specific panel drivers. However, the DT data should be generic. This
brings the issue that some other platform could use the same panels, and
would need to create a driver with the same 'compatible' string as the
OMAP driver.
In the long run, we have to get a common panel framework. For the time
being, this patch solves the issue:
At early boot time, we go through the DT nodes looking for the panels
the kernel supports for OMAP. For each found node, the 'compatible'
string is prepended with "omapdss,", i.e. "sony,acx565akm" becomes
"omapdss,sony,acx565akm". The OMAP display drivers all have "omapdss,"
at the beginning of their compatible field.
This allows us to have generic DT data, but OMAP specific display
drivers.

The OMAP display architecture requires a bunch of platform devices which
are not created via .dts (for now). We also need to pass a few function
pointers and the DSS hardware version from the arch code to omapdss
driver.
This patch adds omapdss_init_of() function, called from board-generic at
init time, which handles those tasks.

When an interrupt has become active on the INTC it will stay active
until it is acked, even if masked or de-asserted. The
INTC_PENDING_IRQn registers are however updated and since these are
used by omap_intc_handle_irq to determine which interrupt to handle,
it will never see the active interrupt. This will result in a storm of
useless interrupts that is only stopped when another higher priority
interrupt is asserted.
Fix by sending the INTC an acknowledge if we find no interrupts to
handle.

The OMAP iommu driver performs the reset management for the
iommu instances in processor sub-systems using the omap_device
API which are currently supplied as platform data ops. Use pdata
quirks to maintain the functionality as the OMAP iommu driver
gets converted to use DT nodes, until the reset portions are
decoupled from omap_hwmod/omap_device into a separate reset
driver.

As OMAP2+ is moving to a full DT boot for all SoC families, commit
7ce93f3 "ARM: OMAP2+: Fix more missing data for omap3.dtsi file"
adds basic DT bits for OMAP3. But the driver is not yet converted,
so this will not work and driver will not be probed. Convert it!
The legacy boot mode is still supported until OMAP3 is converted
to DT-boot only.

The SyncTimer in AM43x is clocked using the following two sources:
1) An inaccuarte 32k clock (CLK_32KHZ) derived from PER DPLL, causing system
time to go slowly (~10% deviation).
2) external 32KHz RTC clock, which may not always be available on board like
in the case of ePOS EVM
Use gptimer as clocksource instead, as is done in the case of AM335x
(which does not have a SyncTimer). With this, system time keeping works

Since commit 65aa94b204 (ARM: OMAP4: clockdomain/CM code: Update supported
transition modes), on OMAP4, all CLKDMs support HW_AUTO so this is used
instead of SW_SLEEP for the idling of clockdomains. However, additional
SoCs now leverage the OMAP4 clockdomain code so update it to use SW_SLEEP
if the clockdomain data specifies that the CLKDM has the
CLKDM_CAN_FORCE_SLEEP flag set rather than using HW_AUTO for both cases.
Without this patch, clockdomain handling is broken on AM43xx and no
clockdomains are actually being put into idle on this platform. Any
attempt to idle them results in the HW_AUTO value (0x3) being written
to them with no apparent effect.

If CLK_SET_RATE_PARENT is set for a clkoutx2 clock, calling
clk_set_rate() on the clock "skips" the x2 multiplier as there are no
set_rate and round_rate functions defined for the clkoutx2.
This results in getting double the requested clock rates, breaking the
display on omap3430 based devices. This got broken when
d0f58bd3bb and related patches were merged
for v3.14, as omapdss driver now relies more on the clk-framework and
CLK_SET_RATE_PARENT.

Merge tag 'dropmachtimexh-v2' of git://git.pengutronix.de/git/ukl/linux into next/cleanup
This cleanup series gets rid of <mach/timex.h> for platforms not using
ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since
387798b (ARM: initial multiplatform support).)
To make this work some code out of arch/arm needed to be adapted. The
respective changes got acks by their maintainers to be taken via armsoc
(with Andrew Morton substituting for Alessandro Zummo as rtc maintainer).
Compared to the previous pull request there was another patch added that
fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not
squash this fix into the original commit to save him from the need to
reverify the series.

Fixes: commit 75d3625e0e
ARM: OMAP2+: gpmc: add DT bindings for OneNAND
OMAP SoC(s) depend on GPMC controller driver to parse GPMC DT child nodes and
register them platform_device for ONENAND driver to probe later. However this does
not happen if generic MTD_ONENAND framework is built as module (CONFIG_MTD_ONENAND=m).
Therefore, when MTD/ONENAND and MTD/ONENAND/OMAP2 modules are loaded, they are unable
to find any matching platform_device and remain un-binded. This causes on board
ONENAND flash to remain un-detected.

CONFIG_MTD_ONENAND=y || CONFIG_MTD_ONENAND=m

The wakeup gen mask/unmask callback uses the irq element of the
irq_data to setup. The irq is the linux virtual irq number and
is same as the hardware irq number only when the parent irqchip
is setup as a legacy domain. When it is used as a linear domain,
the virtual irqs are allocated dynamically and wakeup gen code
cannot rely on these numbers to access the irq registers. Instead
use the hwirq element of the irq_data which represent the physical
irq number.

Here's a set of patches for (hopefully) -rc1. Some of them are fixes,
but a good number of them also do things such as enable new drivers in
the defconfigs for platforms that have such devices, increases coverage
of the multiplatform defconfig and some DTS changes that plumbs up some
of the devices that now have bindings and driver support.

As usual, we have a batch of fixes that weren't considered significant
enough to warrant going into the later -rcs for previous release, so
they are queued up on this branch.
A handful of these are for various DT fixups for Samsung platforms,
and a handful of other minor things.
There are also a couple of stable-marked patches for mvebu -- they came in
quite late and we decided to keep them deferred until the first -stable
release to get more coverage instead of squeezing them into 3.13.

Switch to memblock interfaces for early memory allocator instead of
bootmem allocator. No functional change in beahvior than what it is in
current code from bootmem users points of view.
Archs already converted to NO_BOOTMEM now directly use memblock
interfaces instead of bootmem wrappers build on top of memblock. And
the archs which still uses bootmem, these new apis just fallback to
exiting bootmem APIs.

DT clocks are mostly missing clkdm info now, and this causes an issue with
counter32k which makes its slave idlemode wrong and prevents core idle.
Fixed by initializing the hwmod clkdm pointers for omap3 also which makes
sure the clkdm flag matching logic works properly.
This patch also changes the return value for _init_clkdm to 0 for
incorrect clkdm_name, as this a warning, not a fatal error.

Kexec disables outer cache before jumping to reboot code, but it doesn't
flush it explicitly. Flush is done implicitly inside of l2x0_disable().
But some SoC's override default .disable handler and don't flush cache.
This may lead to a corrupted memory during Kexec reboot on these
platforms.
This patch adds cache flush inside of OMAP4 and Highbank outer_cache.disable()
handlers to make it consistent with default l2x0_disable().

Fix the issue by registering the DPI LCD panel only after the twl4030

Commit 7d7e1eb (ARM: OMAP2+: Prepare for irqs.h removal) and commit
ec2c082 (ARM: OMAP2+: Remove hardcoded IRQs and enable SPARSE_IRQ)
updated the way interrupts for OMAP2/3 devices are defined in the
HWMOD data structures to being an index plus a fixed offset (defined
by OMAP_INTC_START).
Couple of irqs in the OMAP2/3 hwmod data were misconfigured completely
as they were missing this OMAP_INTC_START relative offset. Add this
offset back to fix the incorrect irq data for the following modules:
OMAP2 - GPMC, RNG
OMAP3 - GPMC, ISP MMU & IVA MMU

This adds support for CompuLab SBC-T3530, also known as cm-t3730:

It seems that with the sbc-3xxx mainboard is also used on
SBC-T3517 and SBC-T3730 with just a different CPU module:
http://compulab.co.il/products/sbcs/sbc-t3517/http://compulab.co.il/products/sbcs/sbc-t3730/
So let's add a common omap3-sb-t35.dtsi and then separate SoC
specific omap3-sbc-t3730.dts, omap3-sbc-t3530.dts and
omap3-sbc-t3517.dts.
I've tested this with SBC-T3730 as that's the only one I have.
At least serial, both Ethernet controllers, MMC, and wl12xx WLAN
work.
Note that WLAN seems to be different for SBC-T3530. And SBC-T3517
may need some changes for the EMAC Ethernet if that's used
instead of the smsc911x.

Due to the cross dependencies between hwmod for automanaged device
information for OMAP and dts node definitions, we can run into scenarios
where the dts node is defined, however it's hwmod entry is yet to be
added. In these cases:
a) omap_device does not register a pm_domain (since it cannot find
hwmod entry).
b) driver does not know about (a), does a pm_runtime_get_sync which
never fails
c) It then tries to do some operation on the device (such as read the
revision register (as part of probe) without clock or adequate OMAP
generic PM operation performed for enabling the module.
This causes a crash such as that reported in:
https://bugzilla.kernel.org/show_bug.cgi?id=66441
When 'ti,hwmod' is provided in dt node, it is expected that the device
will not function without the OMAP's power automanagement. Hence, when
we hit a fail condition (due to hwmod entries not present or other
similar scenario), fail at pm_domain level due to lack of data, provide
enough information for it to be fixed, however, it allows for the driver
to take appropriate measures to prevent crash.

In _ocp_softreset(), after _set_softreset() + write_sysconfig(),
the hwmod's sysc_cache will always contain SOFTRESET bit set
so all further writes to sysconfig using this cache will initiate
a repeated SOFTRESET e.g. enable_sysc(). This is true for OMAP3 like
platforms that have RESET_DONE status in the SYSSTATUS register and
so the the SOFTRESET bit in SYSCONFIG is not automatically cleared.
It is not a problem for OMAP4 like platforms that indicate RESET
completion by clearing the SOFTRESET bit in the SYSCONFIG register.
This repeated SOFTRESET is undesired and was the root cause of
USB host issues on OMAP3 platforms when hwmod was allowed to do the
SOFTRESET for the USB Host module.
To fix this we clear the SOFTRESET bit and update the sysconfig
register + sysc_cache using write_sysconfig().

As we currently need to support a mix of legacy platform data and
device tree intialized data, let's make sure things keep working
for the TWL GPIOs.
Mostly the issue is caused by the fact that DSS does not yet have
device tree bindings, so we need to rely on the TWL GPIO callback
for setting up things like LCD backlight for some boards.
As of_platform_populate() for the TWL GPIO is called by twl-core
after the I2C bus has been initialized, we cannot pass the auxdata
table from the board init code to twl-core like we used to with
just legacy platform data.
So let's use the omap_device bus hook to patch in the platform
data for TWL GPIO until we have sorted out the issues with the
TWL GPIOs and device tree bindings.
The other option was be to initialize twl core using legacy
platform data, which seems like a step backwards as we're moving
to device tree only initialization. And we really don't want to
add custom configuration functions to the TWL GPIO driver either
for this.

We have some device tree properties where the ti,hwmod have multiple
values:
am33xx.dtsi: ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
am4372.dtsi: ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
dra7.dtsi: ti,hwmods = "l3_main_1", "l3_main_2";
omap3.dtsi: ti,hwmods = "mcbsp2", "mcbsp2_sidetone";
omap3.dtsi: ti,hwmods = "mcbsp3", "mcbsp3_sidetone";
omap4.dtsi: ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";
omap5.dtsi: ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";
That's not correct way of doing things in this case because these are
separate devices with their own address space, interrupts, SYSCONFIG
registers and can set their PM states independently.
So they should all be fixed up to be separate devices in the .dts files.
We also have the related data removed for at least omap4 in commit
3b9b10151c (ARM: OMAP4: hwmod data: Clean up the data file), so
that data is wrongly initialized as null data.
So we need to fix two bugs:
1. We are only checking the first entry of the ti,hwmods property
This means that we're only initializing the first hwmods entry
instead of the ones listed in the ti,hwmods property.
2. We are only checking the child nodes, not the nodes themselves
This means that anything listed at OCP level is currently just
ignored and unitialized and at least the omap4 case, with the
legacy data missing from the hwmod.
Fix both of the issues by using an index to the ti,hwmods property
and changing the hwmod lookup function to also check the current node
for ti,hwmods property instead of just the children.
While at it, let's also add some warnings for the bad data so it's
easier to fix.

From Tony Lindgren:
Some omap related fixes that have come up with people moving to device
tree only based booting for omap2+.
The series contains a handful of fixes for the igep boards as they were
one of the first omap3 boards to jump over completely to device tree
based booting. So these can be considered regressions compared to
booting igep in legacy mode with board files in v3.12.
Also included are few other device tree vs legacy booting regressions:
- yet more missing omap3 .dtsi entries that have showed up booting
various boards with device tree only
- n900 eMMC device tree fix
- fixes for beagle USB EHCI
- two fixes to make omap2420 MMC work
As we're moving omap2+ to be device tree only for v3.14, I'd like to
have v3.13 work equally well for legacy based booting and device tree
based booting. So there will be likely few more device tree related
booting patches trickling in.
This series also includes a regression fix for the omap timer posted
mode that may wrongly stay on from the bootloader for some SoCs.
