As a second global reset, the GRF is not reset, the iomux and
pull of PWM pin is still keeping, but PWM controller is reset,
PWM pin goes into input mode. However, the pull is still none
changed in kernel, which can cause voltage problems, so should
always keep the PWM pin pull down mode, with 0~50 μA power
increase.

Allow to use tunable delay before detecting card after card is inserted,
which either comes from firmware node, or comes from debounce value
passed on to mmc_gpiod_request_cd(). If the platform doesn't support
debounce, then we fall back to use the debounce period as the delay,
otherwise, it behaves the same as before that a HW debounce(if set) plus
a 200ms hardcode delay before detecting the card.

cd-gpios uses a fixed delay, 200ms, before detecting card after the card
is inserted. 200ms doesn't work for some platforms, so some host drivers
added their own properties for parsing that from DT, for instance,
dw_mmc and pxamci. That being said, it should also be tunable when using
cd-gpios.

Each product needs to create a new driver code, even if
they are using the same TP chip. This creates a lot of
code redundant.

The Neon bit sliced AES decryption store the key schedule in BS_KEY struct,
it introduces a competitive risk，such as dm-crypt without samecpu option.
So backport from linux stable version 4.14.13.

If a regulator is supplied by the DCDC_REG5, and the regulator registers
behind the DCDC_REG5, then some devices can not have the regulator_get()
because the regulator has not get its suplly. The case happen in
rdev_init_debugfs() typically.

Add "suspended" flag in suspend_noirq()/resume_noirq() callback
to prevent new i2c job started, and use i2c_lock_adapter() to wait
for current i2c transfer finished.
If any i2c client try to access I2C after suspend_noirq() or
before resume_noirq() callback, return the error, and they
should fix it, not to start i2c access at this moment.

This patch add support for rockchip voice activity detection.
The vad is used to detect the amplitude of voice which is
received by analog mic, i2s digital mic or pdm digital mic
when soc is in low power mode. if the amplitude of voice is
over threshold, the vad will assert interrupt to wake up soc,
then soc will exit low power mode.
