We get the following warning with the driver is compiled in:
WARNING: modpost: Found 1 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
With CONFIG_DEBUG_SECTION_MISMATCH enabled, the details are reported:
WARNING: vmlinux.o(.text+0x55d014): Section mismatch in reference from the
function fsl_guts_probe() to the function
.init.text:of_flat_dt_get_machine_name()
The function fsl_guts_probe() references
the function __init of_flat_dt_get_machine_name().
This is often because fsl_guts_probe lacks a __init
annotation or the annotation of of_flat_dt_get_machine_name is wrong.
This patch fixes the issue by using the normal DT/OF API rather than
the of_flat_* one.

The function tegra_io_rail_prepare() converts the IO rail ID into a
bit position that is used to check the status and control the IO rail
in the PMC registers. However, rather than converting to a bit position
it is more useful to convert to a bit-mask because this is what is
actually used. By doing so the BIT() marco only needs to be used once
and we can use the IO_DPD_REQ_CODE_MASK when checking for erroneous rail
IDs.

It is possible for the public functions, tegra_io_rail_power_on/off()
to be called before the PMC device has been probed. If this happens
then the pmc->clk member will not be initialised and the call to
clk_get_rate() in tegra_io_rail_prepare() will return zero and lead
to a divide-by-zero exception. The function clk_get_rate() will return
zero if a NULl clk pointer is passed. Therefore, rather that checking
if pmc->clk is initialised, fix this by checking the return value for
clk_get_rate() to make sure it is not zero.

I/O pins on Tegra SoCs are grouped into so-called I/O pads. Each such
pad can be used to control the common voltage signal level and power
state of the pins in the given pad.
I/O pads can be powered down even if the system is active, which can
save power from that I/O interface. For SoC generations prior to
Tegra124 the I/O pad voltage is automatically detected and hence the

The newly introduced pm_genpd_remove reverts the initialization done
by pm_genpd_init and is necessary in the error path of the rockchip
power-domain driver.
Without it the driver will in the error case cleanup the devm-allocated
structures including the elements referenced in the gpd_list thus making
deactivation of unused domains (and probably later genpd accesses as
well) fail by accessing invalid pointers.

Add a driver for the Renesas R-Car Gen1 RESET/WDT and R-Car Gen2/Gen3
and RZ/G RST module.
For now this driver just provides an API to obtain the state of the mode
pins, as latched at reset time. As this is typically called from the
probe function of a clock driver, which can run much earlier than any
initcall, calling rcar_rst_read_mode_pins() just forces an early
initialization of the driver.
Despite the current simple and almost identical handling for all
supported SoCs, the driver matches against SoC-specific compatible
values, as the features provided by the hardware module differ a lot
across the various SoC families and members.

On rk3288 it was important that powerdown and powerup counts for the
CPU/GPU in the kernel because:
* The power on default was crazy long.
* We couldn't rely on the firmware to set this up because really this
wasn't the firmware's job--the kernel was the only one that really
cared about bringing up / down CPUs and the GPU and doing suspend /
resume (which involves bringing up / down CPUs).
On newer ARM systems (like rk3399) ARM Trusted Firmware is in charge of
bringing up and down the CPUs and it really should be in charge of
setting all these counts right. After all ATF is in charge of suspend /
resume and CPU up / down. Let's get out of the way and let ATF do its
job.
A few other motivations for doing this:
* Depending on another configuration (PMU_24M_EN_CFG) these counts can
be either in 24M or 32k cycles. Thus, though ATF isn't really so
involved in bringing up the GPU, ATF should probably manage the counts
for everything so it can also manage the 24M / 32k choice.
* It turns out that (right now) 24M mode is broken on rk3399 and not
being used. That means that the count the kernel was programming
in (24) was not 1 us (which it seems was intended) but was actually
.75 ms
* On rk3399 there are actually 2 separate registers for setting CPU
up/down time plus 1 register for GPU up/down time. The curent kernel
code actually was putting the register for the "little" cores in the
"CPU" slot and the register for the "big" cores in the "GPU" slot. It
was never initting the GPU counts.
Note: this change assumes that ATF will actually set these values at
boot, as I'm proposing in <http://crosreview.com/372381>.

Commit 0e6e01ff69 ("CPM/QE: use genalloc to manage CPM/QE muram")
has changed the way muram is managed.
genalloc uses kmalloc(), hence requires the SLAB to be up and running.
On powerpc 8xx, cpm_reset() is called early during startup.
cpm_reset() then calls cpm_muram_init() before SLAB is available,
hence the following Oops.
cpm_reset() cannot be called during initcalls because the CPM is
needed for console.
This patch removes the call to cpm_muram_init() from cpm_reset().
cpm_muram_init() will be called from a new function called cpm_init()
which is declared as subsys_initcall, unless cpm_muram_alloc() is
called earlier for the serial console in which case cpm_muram_init()
will be called from there.
The reason for calling it from two places is that some drivers
(e.g. i2c-cpm) need some of the initialisations done by
cpm_muram_init() but don't call cpm_muram_alloc(). The console
driver calls cpm_muram_alloc() but some platforms might not use
the CPM serial ports for console.

As the ux500 id code is basically a standalone driver, we can move it
out of the arch code into drivers/soc/ux500.
This is a user-visible change, as it moves all the devices in sysfs
from /sys/devices/soc0/ to /sys/devices/ and leaves the soc0 node as a
separate device.
Originally the idea was to put all on-chip devices under the soc node,
and ux500 was the first platform to have this device, but later platforms
almost all didn't follow that pattern, so this makes the platform do
the same thing as everyone else.
Since the platform is really obsolete now, I am optimistic that nothing
will break after moving the devices around.
As the SoC driver no longer has access to the private header files,
I'm changing the code to instead look up the address of the backupram
from devicetree, which is a good idea anyway.
Finally, having a separate Kconfig symbol means the driver is now
optional and could even be a loadable module rather than always being
built-in if we allowed that for soc_device.

If CONFIG_PM_GENERIC_DOMAINS is not enabled, then power partitions
associated with a device will not be enabled automatically by the PM
core when the device is in use. To avoid situations where a device in
a power partition is to be used but the partition is not enabled,
initialise the power partitions for Tegra early in the boot process and
if CONFIG_PM_GENERIC_DOMAINS is not enabled, then power on all
partitions defined in the device-tree blob.
Note that if CONFIG_PM_GENERIC_DOMAINS is not enabled, after the
partitions are turned on, the clocks and resets used as part of the
sequence for turning on the partition are released again as they are no
longer needed by the PMC driver. Another benefit of this is that this
avoids any issues of sharing resets between the PMC driver and other
device drivers that may wish to independently control a particular
reset.

Commit 0259f522e0 ('soc/tegra: pmc: Restore base address on probe
failure') fixes an issue where the PMC base address pointer is not
restored on probe failure. However, this fix creates another problem
where if early initialisation of the PMC driver fails and an initial
mapping for the PMC address space is not created, then when the PMC
device is probed, the PMC base address pointer will not be valid and
this will cause a crash when tegra_pmc_init() is called and attempts
to access a register.
Although the PMC address space is mapped a 2nd time during the probe
and so this could be fixed by populating the base address pointer
earlier during the probe, this adds more complexity to the code.
Moreover, the PMC probe also assumes the the soc data pointer is also
initialised when the device is probed and if not will also lead to a
crash when calling tegra_pmc_init_tsense_reset(). Given that if the
early initialisation does fail then something bad has happen, it seems
acceptable to allow the PMC device probe to fail as well. Therefore, if
the PMC base address pointer or soc data pointer are not valid when
probing the PMC device, WARN and return an error.

possible to ensure it will always be initialised.

The public functions exported by the PMC driver use the presence of the
SoC data pointer to determine if the PMC device is configured and the
registers can be accessed. However, the SoC data is populated before the
PMC register space is mapped and this opens a window where the SoC data
pointer is valid but the register space has not yet been mapped which
could lead to a crash. Furthermore, if the mapping of the PMC register
space fails, then the SoC data pointer is not cleared and so would
expose a larger window where a crash could occur.
Fix this by initialising the SoC data pointer after the PMC register
space has been mapped.

During early initialisation, the available power partitions for a given
device is configured as well as the polarity of the PMC interrupt. Both
of which should only be configured if there is a valid device node for
the PMC device. This is because the soc data used for configuring the
power partitions is only available if a device node for the PMC is found
and the code to configure the interrupt polarity uses the device node
pointer directly.
Some early device-tree images may not have this device node and so fix

The function tegra_power_sequence_power_up() is a public function used
to power on a partition. When this function is called, we do not check
to see if the partition being powered up is valid/available. Fix this
by checking to see that the partition is valid/available.

When registering the Tegra power partitions with the generic PM domain
framework, the current state of the each partition is checked and used
as the default state for the partition. However, the state of each reset
associated with the partition is not initialised and so it is possible
that the state of the resets are not in the expected state. For example,
if a partition is on, then the resets should be de-asserted and if the
partition is off, the resets should be asserted.
There have been cases where the bootloader has powered on a partition
and only de-asserted some of the resets to some of the devices in the
partition. This can cause accesses to these devices to hang the system
when the kernel boots and attempts to probe these devices.
Ideally, the driver for the device should ensure the reset has been
de-asserted when probing, but the resets cannot be shared between the
PMC driver (that needs to de-assert/assert the reset when turning the
partition on or off) and another driver because we cannot ensure the
reset is in the correct state.
To ensure the resets are in the correct state, when using the generic
PM domain framework, put each reset associated with the partition in
the correct state (based upon the partition's current state) when
obtaining the resets for a partition.

Align SYSC interrupt configuration in the legacy wrapper with the DT
version:
- Mask SYSC interrupt sources before enabling them (doesn't matter
much as they're disabled at the GIC level anyway),
- Make sure not to clear reserved SYSCIMR bits that were set before.

On R-Car H1 and Gen2, the SYSC interrupt registers are always configured
using hardcoded values in platform code. For R-Car Gen2, values are
provided for H2 and M2-W only, other SoCs are not yet supported, and
never will be.
Move this configuration from SoC-specific platform code to the
rcar_sysc_init() wrapper, so it can be skipped if the SYSC is configured
from DT. This would be the case not only for H1, H2, and M2-W using a
modern DTS, but also for other R-Car Gen2 SoCs not supported by the
platform code, relying purely on DT.
There is no longer a need to return the mapped register block, hence
make the function return void.

We need the signal from wcnss_ctrl indicating that the firmware is up

mtk-pmic-wrap.c:1086:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
.int_en_all = ~(BIT(31) | BIT(1)),
The problem is that the result of the BIT() macro is an 'unsigned long',
so taking the bitwise NOT operation of that results in an integer
with the upper 32 bits all set and that cannot be assigned to a
'u32' variable without loss of information.
This is harmless because we were never interested in the upper bits
here anyway, so we can shut up the warning by adding a simple cast
to 'u32'.

Driver updates for ARM SoCs, these contain various things that touch
the drivers/ directory but got merged through arm-soc for practical
reasons. For the most part, this is now related to power management
controllers, which have not yet been abstracted into a separate
subsystem, and typically require some code in drivers/soc or arch/arm
to control the power domains.
Another large chunk here is a rework of the NVIDIA Tegra USB3.0
support, which was surprisingly tricky and took a long time to
get done.
Finally, reset controller handling as always gets merged through here
as well.

Traditionally we've had two separate branches for cleanups and non-critical

The most notably change is for OMAP, which gets a small rework to simplify
handling of the AUXDATA mechanism used on machines that are not completely
DT based yet, along with other work that is used as preparation for dropping
the legacy board files.

Merge tag 'armsoc-cleanups-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups and fixes from Arnd Bergmann:
"Traditionally we've had two separate branches for cleanups and
non-critical bug fixes, but both of these got smaller with each
release and the differences are rather unclear now, so it seems more
appropriate to have a combined branch.
The most notable change is for OMAP, which gets a small rework to
simplify handling of the AUXDATA mechanism used on machines that are
not completely DT based yet, along with other work that is used as
preparation for dropping the legacy board files"
* tag 'armsoc-cleanups-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
ARM: dts: exynos: Add interrupt line to MAX8997 PMIC on exynos4210-trats
ARM: dts: exynos: Fix regulator name to avoid forbidden character on exynos4210-trats
ARM: dts: exynos: Add MFC memory banks for Peach boards
ARM: OMAP2+: n900 needs MMC slot names for legacy user space
ARM: OMAP2+: Add more functions to pwm pdata for ir-rx51
ARM: debug: remove extraneous DEBUG_HI3716_UART option
ARM: OMAP2+: Simplify auxdata by using the generic match
of/platform: Allow secondary compatible match in of_dev_lookup
ARM: davinci: use IRQCHIP_DECLARE for cp_intc
ARM: davinci: remove unused DA8XX_NUM_UARTS
ARM: davinci: simplify call to of populate
ARM: DaVinci USB: removed deprecated properties from MUSB config
ARM: rockchip: Fix use of plain integer as NULL pointer
ARM: realview: hide unused 'pmu_device' object
soc: versatile: dynamically detect RealView HBI numbers
Core infrastructural changes:
- Support for natively single-ended GPIO driver stages. This
means that if the hardware has registers to configure open
drain or open source configuration, we use that rather than
(as we did before) try to emulate it by switching the line
to an input to get high impedance. This is also documented
throughly in Documentation/gpio/driver.txt for those of you
who did not understand one word of what I just wrote.
- Start to do away with the unnecessarily complex and
unitelligible ARCH_REQUIRE_GPIOLIB and
ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from
the time when the GPIO subsystem was unmaintained. Archs can
now just select GPIOLIB and be done with it, cleanups to
arches will trickle in for the next kernel. Some minor archs
ACKed the changes immediately so these are included in this
pull request.
- Advancing the use of the data pointer inside the GPIO device
for storing driver data by switching the PowerPC, Super-H
Unicore and a few other subarches or subsystem drivers in
ALSA SoC, Input, serial, SSB, staging etc to use it.
- The initialization now reads the input/output state of the
GPIO lines, so that each GPIO descriptor knows - if this
callback is implemented - whether the line is input or
output. This also reflects nicely in userspace "lsgpio".
- It is now possible to name GPIO producer names, line names,
from the device tree. (Platform data has been supported for
a while.) I bet we will get a similar mechanism for ACPI
one of those days. This makes is possible to get sensible
producer names for e.g. GPIO rails in "lsgpio" in userspace.
New drivers:
- New driver for the Loongson1.
- The XLP driver now supports Broadcom Vulcan ARM64.
- The IT87 driver now supports IT8620 and IT8628.
- The PCA953X driver now supports Galileo Gen2.
Driver improvements:
- MCP23S08 was switched to use the gpiolib irqchip helpers and
now also suppors level-triggered interrupts.
- 74x164 and RCAR now supports the .set_multiple() callback
- AMDPT was converted to use generic GPIO.
- TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
support the new single ended callback for open drain
and in some cases open source.
- Implement the .get_direction() callback for a few more drivers
like PL061, Xgene.
Cleanups:
- Paul Gortmaker combed through the drivers and de-modularized
those who are not really modules.
- Move the GPIO poweroff DT bindings to the power subdir where
they belong.
- Rename gpio-generic.c to gpio-mmio.c, which is much more to the
point. That's what it is handling, nothing more, nothing less.

Adds generic PM domain support to the PMC driver where the PM domains
are populated from device-tree and the PM domain consumer devices are
bound to their relevant PM domains via device-tree as well.
Update the tegra_powergate_sequence_power_up() API so that internally
it calls the same tegra_powergate_xxx functions that are used by the
Tegra generic PM domain code for consistency.
To ensure that the Tegra power domains (a.k.a. powergates) cannot be
controlled via both the legacy tegra_powergate_xxx functions as well
as the generic PM domain framework, add a bit map for available
powergates that can be controlled via the legacy powergate functions.
Move the majority of the tegra_powergate_remove_clamping() function
to a sub-function, so that this can be used by both the legacy and
generic power domain code.

On R-Car H3, some power areas (e.g. A3VP) contain I/O devices, which are
also part of the CPG/MSSR Clock Domain.
On all R-Car SoCs, devices in the "always-on" PM Domain are part of the
Clock Domain served by the CPG/MSSR or CPG/MSTP driver.
Hook up the CPG/MSTP or CPG/MSSR Clock Domain attach/detach callbacks to
enable power management using module clocks. Which callback to hook up
depends on the presence of device nodes compatible with
"renesas,cpg-mstp-clocks". This clears the path for a future migration
from the CPG/MSTP to the CPG/MSSR driver on R-Car H1 and
Gen2.

Populate the SYSC PM domains from DT, based on the presence of a device
node for the System Controller. The actual power area hiearchy, and
features of specific areas are obtained from tables in the C code.
The SYSCIER and SYSCIMR register values are derived from the power areas
present, which will help to get rid of the hardcoded values in R-Car H1
and R-Car Gen2 platform code later.
Initialization is done from an early_initcall(), to make sure the PM
Domains are initialized before secondary CPU bringup.

Move the pm-rcar driver from arch/arm/mach-shmobile/ to
drivers/soc/renesas/, and its header file to include/linux/soc/renesas/,
so it can be shared between arm32 (R-Car H1 and Gen2) and arm64 (R-Car
Gen3). Rename it to rcar-sysc as it's really a driver for the R-Car
System Controller (SYSC).
Kill the intermediate PM_RCAR config symbol, as it's not user
configurable anymore, and to prepare for SoC-specific make rules.
Add the missing #include <linux/types.h> to rcar-sysc.h, which was
exposed by different include order.

With more SoCs being added the list of helper functions like these would
grow. To mitigate this problem we remove the existing helpers and change
the code to test against the pmic type stored inside the pmic specific
datastructure that our context structure points at. There is one usage of
pwrap_is_mt8135() that is ambiguous as the test should not be dependent on
mt8135, but rather on the existence of a bridge. Add a new element to
pmic_wrapper_type to indicate if a bridge is present and use this where
appropriate.
