This driver parses the reboot commands like "reboot bootloader"
and "reboot recovery" to get a boot mode described in the
device tree , then call the write interfae to store the boot
mode in some place like special register or sram, which can
be read by the bootloader after system reboot, then the bootloader
can take different action according to the mode stored.This is commonly used on Android based devices, in order to
reboot the device into fastboot or recovery mode.Reviewed-by: Matthias Brugger

power_supply_get_property() should ideally return -EAGAIN if it is
called while the power_supply is being registered. There was no way
previously to determine if use_cnt == 0 meant that the power_supply
wasn't fully registered yet, or if it had already been unregistered.Add a new boolean to the power_supply struct to simply show if
registration is completed. Lastly, modify the check in
power_supply_show_property() to also ignore -EAGAIN when so it
doesn't complain about not returning the property.Signed-off-by: Rhyland Klein

Prior to this commit a zero gpio was treated as invalid. Whereas

The max8903_charger.h file indicated that dcm and dok were not optional
when dc_valid is set.It makes sense to have dok as a compulsory pin when dc_valid is given.
However dcm can be optionally wired to a fixed level especially when the
circuit is configured for dc power exclusively.The previous implementation already allowed for this somewhat, however no
error was given if dok wasn't given whilst dc_valid was.The new implementation enforces dok presence when dc_valid is given. Whilst
allowing dcm to be optional.Signed-off-by: Chris Lapa

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

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

This adds the necessary data for handling io voltage domains on the rk3399.
As interesting tidbit, the rk3399 contains two separate iodomain areas.
One in the regular General Register Files (GRF) and one in PMUGRF in the
pmu power domain.Signed-off-by: David Wu
