IO-domain handling is part of the general register files, so should live
under the grf directly. This change allows the grf to be a simple-mfd and
the io-domains fetching the syscon regmap from that parent-node.
The old binding is of course preserved, though deprecated.

POWER_SUPPLY_STATUS_NOT_CHARGING is used for AC connected, but
battery not charging (e.g. because battery temperature is out
of acceptable range).
When battery is charging near dry and BATTERY_FULL_DISCHARGED is set,
it is wrong to set as POWER_SUPPLY_STATUS_NOT_CHARGING.
Just use BATTERY_DISCHARGING to decide the power supply status is
discharging or charging.

We accidentally free "micro_ac_power" which is an error pointer and it

We were freeing "info->battery" instead of "info->usb", which leads to
an OOps and a resource leak.
The labels were wonky, "out_battery" did release the battery but out_usb
did not release usb. I was introducing a call to free usb so it sort
conflicted with existing misleading name. I renamed them.

Sama5d2 SoC has a completely new shutdown controller with new features and
register layout. It thus makes sense to add a new driver for this new
peripheral.
This driver is Device Tree only and handles events from the wake-up pin and
the RTC.
As the register layout may change in the future, so some values are encoded
in a configuration structure.

Pull more power management and ACPI updates from Rafael Wysocki:
"The second batch of power management and ACPI updates for v4.6.
Included are fixups on top of the previous PM/ACPI pull request and
other material that didn't make into it but still should go into 4.6.
Among other things, there's a fix for an intel_pstate driver issue
uncovered by recent cpufreq changes, a workaround for a boot hang on
Skylake-H related to the handling of deep C-states by the platform and
a PCI/ACPI fix for the handling of IO port resources on non-x86
architectures plus some new device IDs and similar.
Specifics:
- Fix for an intel_pstate driver issue related to the handling of MSR
updates uncovered by the recent cpufreq rework (Rafael Wysocki).
- cpufreq core cleanups related to starting governors and frequency
synchronization during resume from system suspend and a locking fix
for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).
- acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
Michael Neuling, Richard Cochran, Shilpasri Bhat).
- intel_idle driver update preventing some Skylake-H systems from
hanging during initialization by disabling deep C-states mishandled
by the platform in the problematic configurations (Len Brown).
- Intel Xeon Phi Processor x200 support for intel_idle
(Dasaratharaman Chandramouli).
- cpuidle menu governor updates to make it always honor PM QoS
latency constraints (and prevent C1 from being used as the fallback
C-state on x86 when they are set below its exit latency) and to
restore the previous behavior to fall back to C1 if the next timer
event is set far enough in the future that was changed in 4.4 which
led to an energy consumption regression (Rik van Riel, Rafael
Wysocki).
- New device ID for a future AMD UART controller in the ACPI driver
for AMD SoCs (Wang Hongcheng).
- Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
scaling (AVS) driver (David Wu).
- ACPI PCI resources management fix for the handling of IO space
resources on architectures where the IO space is memory mapped
(IA64 and ARM64) broken by the introduction of common ACPI
resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).
- Fix for the ACPI backend of the generic device properties API to
make it parse non-device (data node only) children of an ACPI
device correctly (Irina Tirdea).
- Fixes for the handling of global suspend flags (introduced in 4.4)
during hibernation and resume from it (Lukas Wunner).
- Support for obtaining configuration information from Device Trees
in the PM clocks framework (Jon Hunter).
- ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
King, Geert Uytterhoeven)"

This adds the necessary data for handling io voltage domains on the rk3399.

The pm2301 charger driver uses nested #ifdefs to check for both
CONFIG_PM and CONFIG_PM_SLEEP in an attempt to hide its
suspend and runtime-pm operations when they are unused, but
it does not hide the clear_lpn_pin() function in the same
way, so we get a build warning when everything is
disabled:
drivers/power/pm2301_charger.c:123:13: error: 'clear_lpn_pin' defined but not used [-Werror=unused-function]
This removes all the #ifdef and instead uses __maybe_unused
annotations to let the compiler know it can silently drop
the function definition.
For the PM2XXX_PM_OPS, we can use an IS_ENABLED() check
to avoid defining the structure when CONFIG_PM is not set without
the #ifdef.

Currently the reset/power off handlers (POWER_RESET) and Adaptive Voltage
Scaling class (POWER_AVS) are not built when POWER_SUPPLY is disabled.
The POWER_RESET is also not visible in drivers main section of config.
However they do not really depend on power supply so they can be built
always. The objects for power supply drivers already depend on
particular Kconfig symbols so there is no need for any changes in
drivers/power/Makefile.
This allows selecting POWER_RESET from main drivers config section and
fixes following build warning (encountered on ARM exynos defconfig when
POWER_SUPPLY is disabled manually):
warning: (ARCH_HISI && ARCH_INTEGRATOR && ARCH_EXYNOS && ARCH_VEXPRESS && REALVIEW_DT) selects POWER_RESET which has unmet direct dependencies (POWER_SUPPLY)

The ds278x_battery_ops structure is never modified, so declare it as const.
Done with the help of Coccinelle.

"of_node_put"
The of_node_put() function tests whether its argument is NULL and then
returns immediately. Thus the test around the calls is not needed.
This issue was detected by using the Coccinelle software.
