Let configuration start and count be performed at the
same time as much as possible, which can reduce the
interval between the start signal and the data signal,
and can also reduce a start irq.

If the slave hold the scl low for a long time, we will send
the stop because the i2c transfer is timeout. Then reset the
slave, the scl will be released to high by slave, the data
hold low, but the controller's state is messy now, need to
disable i2c controller, it is better to reset i2c controller,
it will go back to normal state.
The log like this:
[ 117.444700] rk3x-i2c ff3d0000.i2c: timeout, ipd: 0x93, state: 2
[ 118.466410] rk3x-i2c ff3d0000.i2c: timeout, ipd: 0x00, state: 1

In the TRX mode, if there was a nack signal at the hardware's
tx, we can get start and nack ipd from the I2C_IPD register,
which will enter nack process, send stop command, change the
state to stop, and enter the handler of stop irq, but the stop
irq may not be generated, it has a latency. So the log will like
this:
[ 69.961944] rk3x-i2c ff650000.i2c: unexpected irq in STOP: 0x10
[ 70.959690] rk3x-i2c ff650000.i2c: timeout, ipd: 0x00, state: 4
This error log will confuse us, it is not easier to locate the problem,
we should get nack error at this time, and processing stop interrupt at
the next, then complete this i2c job.

Add "suspended" flag in suspend_noirq()/resume_noirq() callback
to prevent new i2c job started, and use i2c_lock_adapter() to wait

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.

If the system rebooted, there might be i2c transfer at the
same time, it will make something unpredictable, because
the i2c host was reset, but the slave device wasn't, such
as rk808 pmic, so make sure the i2c transfer to be finished
before system shutdown at the reset mode.
This call chain is expected to be executed before kernel_restart
to do something before reset system. such as, i2c restart,
boot mode config.

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

If the PWM pinctrl uses default state, the iomux setting will
be done at probe, the PWM may not be enabled at this moment.
It will make PWM into an intermediate state, destroy the default
hardware state, the PWM is not ready for work yet. So it is better
for doing PWM pinctrl setting after PWM enabled.

This patch is based on https://patchwork.kernel.org/patch/9801533,
add the drm property "hdmi_output_format", the possible value
could be:
- RGB
- YCBCR 444
- YCBCR 422
To handle various subsampling of YCBCR output types, this property
allows two special automatic cases:
- DRM_HDMI_OUTPUT_YCBCR_HQ
This indicates preferred output should be YCBCR output,
with highest subsampling rate by the source/sink, which
can be typically:
- ycbcr444
- ycbcr422
- ycbcr420
- DRM_HDMI_OUTPUT_YCBCR_LQ
This indicates preferred output should be YCBCR output, with
lowest subsampling rate supported by source/sink, which can be:
- ycbcr420
- ycbcr422
- ycbcr444
Default value of the property is set to 0 = RGB, so no changes if you
don't set the property.

- Automatic
This indicates prefer highest color depth, it is
30bit on rockcip platform.
- 24bit
- 30bit
The default value of property is 24bit.
The max_tmds_clock is 0 on some display device, we think it's
max_tmds_clock is 340MHz.
If tmdsclock > max_tmds_clock, real output color depth fallback
to 24bit.
