The gc2145 always rewrite init setting,
when change state from preview to capture.
That will get exposure time again when capture picture,
it causes capture exposure time different with preview.
To fix this issue, following changes introduced:
- reconfig gc2145 reg_table.
- add gc2145_aec_ctrl function calculate Capture shutter.

Now a regulator device can supply multiple consumers at the same time,
if a consumer starts and set a low voltage, another consumer doesn't
start in kernel but has been set a high frequency in bootloader will
abort.
This patch Adds support to limit min_uV during kernel startup to make
sure the voltage can suit the needs of all consumers.

The power_allocator thermal governor should get utilization of cooling
device to calculate dynamic power, but the powersave, userspace and performance
devfreq governor don't updade stats, so the utilization is inaccurate.
This patch adds support to update status when get requested power, so that
power_allocator can also work properly when use powersave, userspace and
performance devfreq governor.

After a cpufreq transition, update the clockevent's frequency
by fetching the new clock rate from the clock framework and
reprogram the next clock event.
The clock supplying the arm-global-timer on the rk3188 is coming
from the the cpu clock itself and thus changes its rate everytime
cpufreq adjusts the cpu frequency.
Found by code review, real impact not known. Assume what actual
HZ value will be different from expected on platforms using
arm-global-timer as clockevent.
The patch is port of commit 4fd7f9b128 ("ARM: 7212/1: smp_twd:
reconfigure clockevents after cpufreq change") and
commit 2b25d9f64b ("ARM: 7535/1: Reprogram smp_twd based on
new common clk framework notifiers").

The "host1" port (AKA the dwc2 port that isn't the OTG port) on rk3288
has a hardware errata that causes everything to get confused when we get
a remote wakeup. We'll use the reset that's in the CRU to reset the
port when it's in a bad state.
Note that we add the reset to both dwc2 controllers even though only one
has the errata in case we find some other use for this reset that's
unrelated to the current hardware errata. Only the host port gets the
quirk property, though.
