Whilst it doesn't matter if the internal 32k clock register settings
are cleaned up on exit, as the part will be turned off losing any
settings, hence the driver hasn't historially bothered. The external
clock should however be cleaned up, as it could cause clocks to be
left on, and will at best generate a warning on unbind.
Add clean up on both the probe error path and unbind for the 32k

Core changes:
- A new GPIO aggregator driver has been merged: this can
join a few select GPIO lines into a new aggregated GPIO
chip. This can be used for security: a process can be
granted access to only these lines, for example for
industrial control. Another way to use this is to
reexpose certain select lines to a virtual machine or
container.
- Warn if the gpio-line-names is too long in he DT parser
core.
- GPIO lines can now be looked up by line name in addition
to being looked up by offset.
New drivers:
- A new generic regmap GPIO driver has been merged. Too
many regmap drivers are starting to look like each other
so we need to create some common ground and try to move
drivers over to using that.
- The F7188X driver now supports F81865.
Driver improvements:
- Large improvements to the PCA953x expander, get multiple lines
and several cleanups.
- Large improvements to the DesignWare DWAPB driver, and Sergey
Semin has volunteered to maintain it.
- PL061 can now be built as a module, this is part of a bigger

One new platform gets added, the Realtek RTD1195, which is an older
Cortex-a7 based relative of the RTD12xx chips that are already supported
in arch/arm64. The platform may also be extended to support running
32-bit kernels on those 64-bit chips for memory-constrained machines.
In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742,
an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally
released in 2016 as one of the last high-end 32-bit designs.
There is ongoing cleanup for the integrator, tegra, imx, and omap2
platforms, with integrator getting very close to the goal of having
zero code in arch/arm/, and omap2 moving more of the chip specifics
from old board code into device tree files.
The Versatile Express platform is made more modular, with built-in
drivers now becoming loadable modules. This is part of a greater effort
for the Android OS to have a common kernel binary for all platforms and
any platform specific code in loadable modules.
The PXA platform drops support for Compulab's pxa2xx boards that had
rather unusual flash and PCI drivers but no known users remaining.
All device drivers specific to those boards can now get removed as
well.
Across platforms, there is ongoing cleanup, with Geert and Rob

The MAX77620 doesn't support bulk writes, so make sure the regmap code
breaks bulk writes into multiple single-byte writes.
Note that this is mostly cosmetic because currently only the RTC sub-
driver uses bulk writes and the RTC driver ends up using a different
regmap on the MAX77620 anyway. However, it seems like a good idea to
make this change now in order to avoid running into issues if bulk
writes are ever used by other sub-drivers sometime down the road.

When runtime PM is enabled, regulators are being controlled by the
driver's suspend and resume callbacks. They are also unconditionally
enabled at driver's probe(), and disabled in remove() functions. Add
more calls to runtime PM framework to ensure that the device's runtime
PM state matches the regulators state:
1. at the end of probe() function: set runtime PM state to active, so
there will be no spurious call to resume();
2. in remove(), ensure that resume() is called before disabling runtime PM
management and unconditionally disabling the regulators.

that driver also provides consumer-supply mapping for the them. If that
driver is not yet loaded, regulator core substitute them with dummy

The "sys_id", "sys_misc" and "sys_procid" devices don't have a user

Nothing in the VExpress sysregs nor the MFD child drivers use
CONFIG_CLKSRC_MMIO. There's the 24MHz counter, but that's handled by
drivers/clocksource/timer-versatile.c which doesn't use
CONFIG_CLKSRC_MMIO either. So let's just drop CONFIG_CLKSRC_MMIO.
As the !ARCH_USES_GETTIMEOFFSET dependency was added for
CONFIG_CLKSRC_MMIO, that can be dropped, too.

vexpress_flags_set() is only used by the platform SMP related code and
has nothing to do with the vexpress-sysreg MFD driver other than both
access the same h/w block. It's also only needed for 32-bit systems and
must be built-in for them. Let's move vexpress_flags_set() closer to
where it is being used. This will allow for vexpress-sysreg to be built

This driver only creates a bunch of platform devices sharing resources
belonging to the PMC device. This is pretty much what MFD subsystem is
for so move the driver there, renaming it to intel_pmc_bxt.c which
should be more clear what it is.
MFD subsystem provides nice helper APIs for subdevice creation so
convert the driver to use those. Unfortunately the ACPI device includes
separate resources for most of the subdevices so we cannot simply call
mfd_add_devices() to create all of them but instead we need to call it
separately for each device.
The new MFD driver continues to expose two sysfs attributes that allow
userspace to send IPC commands to the PMC/SCU to avoid breaking any
existing applications that may use these. Generally this is bad idea so
document this in the ABI documentation.

The SCU IPC functionality is usable outside of Intel MID devices. For
example modern Intel CPUs include the same thing but now it is called
PMC (Power Management Controller) instead of SCU. To make the IPC
available for those split the driver into core part (intel_scu_ipc.c)
and the SCU PCI driver part (intel_scu_pcidrv.c) which then calls the
former before it goes and creates rest of the SCU devices. The SCU IPC
will also register a new class that gets assigned to the device that is
created under the parent PCI device.
We also split the Kconfig symbols so that INTEL_SCU_IPC enables the SCU
IPC library and INTEL_SCU_PCI the SCU driver and convert the users
accordingly. While there remove default y from the INTEL_SCU_PCI symbol
as it is already selected by X86_INTEL_MID.

With the device tree property "rockchip,system-power-controller" we
explicitly request to use this PMIC to power off the system. So always
register our poweroff function, even if some other handler (probably
PSCI poweroff) was registered before.
This does tend to reveal a warning on shutdown due to the Rockchip I2C
driver not implementing an atomic transfer method, however since the
write to DEV_OFF takes effect immediately the I2C completion interrupt
is moot anyway, and as the very last thing written to the console it is
only visible to users going out of their way to capture serial output.

The current codebase makes use of the zero-length array language

variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

the VDSO to its checkpointed location.
- Restore the MIPS32 cBPF JIT, after having reverted the enablement
of the eBPF JIT for MIPS32 systems in the 5.5 cycle.
- Improve cop0 counter synchronization behaviour whilst onlining CPUs
by running with interrupts disabled.
- Better match FPU behaviour when emulating multiply-accumulate
instructions on pre-r6 systems that implement IEEE754-2008 style
MACs.
- Loongson64 kernels now build using the MIPS64r2 ISA, allowing them
to take advantage of instructions introduced by r2.
- Support for the Ingenic X1000 SoC & the really nice little CU Neo
development board that's using it.
- Support for WMAC on GARDENA Smart Gateway devices.
- Lots of cleanup & refactoring of SGI IP27 (Origin 2*) support in
preparation for introducing IP35 (Origin 3*) support.
- Various Kconfig & Makefile cleanups"

There are a lot of similar global registers being used across multiple SoCs
from Unisoc. But most of these registers are assigned with different offset
for different SoCs. It is hard to handle all of them in an all-in-one
kernel image.
Add a helper function to get regmap with arguments where we could put some
extra information such as the offset value.

Both manual and power on resets have a brief period where the chip will
not be accessible immediately afterwards. Extend the time allowed for
this from a minimum of 1mS to 2mS based on newer evaluation of the
hardware and ensure this reset happens in all reset conditions. Whilst
making the change also remove the redundant NULL checks in the reset
functions as the GPIO functions already check for this.

"SAMSUNG" is not an abbreviation but a regular trademarked name.
Therefore it should be written with lowercase letters starting with

Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in

On AXP288 and newer PMICs, bit 7 of AXP20X_VBUS_IPSOUT_MGMT can be set
to prevent using the VBUS input. However, when the VBUS unplugged and
plugged back in, the bit automatically resets to zero.
We need to set the register as volatile to prevent regmap from caching
that bit. Otherwise, regcache will think the bit is already set and not
write the register.

AB8505 support was never fully converted to the device tree.
Most of the MFD cells for AB8505 lack an "of_compatible",
which prevents them from being configured through the device tree.
Align the definition of the AB8505 MFD cells with the ones for AB8500,
and add device tree compatibles. Except for GPIO and regulators the
compatibles are equal to those used for AB8500 because the hardware
does not differ much.
Finally, change db8500_prcmu_register_ab8500() to check for the AB8505
device tree node additionally, and probe it if it is found.
