This removes build warning when COMPILE_TEST=y and MFD_STM32_TIMERS=n
in drivers/pwm/pwm-stm32.c. In function 'stm32_pwm_capture' 'raw_prd' and
'raw_dty' may be used uninitialized in this function

Add device tree bindings for the Dialog DA9063L. This is a
variant of the DA9063 chip with smaller package, with less
LDO regulators and without RTC block. The other properties
of the chip are the same, including the content of the chip
ID register.

while iDMA 64-bit has only one.
Rename it accordingly. Note, there is no functional change since

The cros_ec_i2c driver is still active after it had suspended or before it
resumes. Besides that, it also tried to transfer data even after the I2C
host had been suspended. This will lead the system to crash.
During the test, we also observe that the EC needs to be resumed earlier
due to some status polling from the EC FW (e.g. battery status). So we
move the PM ops to late stage to make it work normally.

If we cannot communicate with the EC chip to detect the protocol version
and its features, it's very likely useless to continue. Else we will
commit all kind of uninformed mistakes (using the wrong protocol, the
wrong buffer size, mixing the EC with other chips).

When AXP806 support was added, POK was incorrectly expanded to PWROK.
However, the datasheet lists them as POK[LSNP], which is the same as
on the AXP288. Furthermore, the registers associated with POK functions
are the same as the PEK on the other AXP PMICs. This suggests that
"POK" means "Power On Key", much like "PEK" means "Power Enable Key",
instead of "Power OK".
This patch changes the "PWROK" prefix to "POK" for these interrupts.

Now GPIOD has support for both pdata systems and for non-standard DT
bindings the Arizona reset GPIO can be converted to use it. Worth
noting gpiod_set_raw_value_cansleep is used to match the behaviour
of the old GPIOs. This is because the part is fairly widely used and
it is unknown how many DTs are correctly setting active low through
device tree, so to avoid breaking any existing users it is best to
match the previous behaviour.
