The RK809 and RK817 are a Power Management IC (PMIC) for multimedia
and handheld devices. They contains the following components:
- Regulators
- RTC
- Clocking
Both RK809 and RK817 chips are using a similar register map,
so we can reuse the RTC and Clocking functionality.
Most of regulators have a some implementation also.

if there are lots of irqs for a device and the register addresses for these
irqs is continuous, we can use this macro to initialize regmap_irq value.

Now we set the load of fixed rate scene to 100%, it isn't accurate,
it is better to update stats if auto freq is enabled.

Now the DW-HDMI Controller supports the HDMI2.0 modes, enable support
for these modes in the connector if the platform supports them.
We limit these modes to DW-HDMI IP version >= 0x200a which
are designed to support HDMI2.0 display modes.

If sink doesn't support YCBCR420 deep color, we return default
8bit.
In YCBCR420 mode, tmdsclock is half of RGB444 mode.

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.

This patch introduce a drm property hdmi_output_depth to
get/set HDMI color depth, the possible value could be
- 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.

According to HDMI spec 1.4, YCbCr422 is also 36-bit mode, so
we remove the override of color format when parsing hdmi deep
color info. And record hdmi YCbCr444 deep color info in
edid_hdmi_dc_modes.
The edid_hdmi_dc_modes should be clean up when parsing EDID.

In interlace mode(480i60hz) the frame rate is 30hz, this is too low and
lead to CTS test failed, so we use field start interrupt instead of
frame start, and the vsync will update to 60hz.

Three operating mode are available to convey the graphical data
to the display:
- Video mode streams over the high-speed link the RGB data and the
associated synchronization signals directly generated by the LCDC.
The streaming starts as soon as the DSI Host and the LCDC are enabled.
This continuous refresh is the best way to interface with a display
without Graphics RAM.
- APB command mode sends commands over the high-speed link for
configuration as it is done using a legacy serial interface (SPI).
The commands are launched using the DSI Host APB interface.
- Adapted command mode is the best way to interface with a display
having its own internal Graphics RAM. The DSI Host captures only
one full frame coming from the LCDC and transforms it into a series
of write commands to update the display Graphics RAM.

In order to enhance the overall robustness of the system, DSI defines
a dedicated EoT packet (EoTp) at the protocol layer for signaling
the end of HS transmission. For backwards compatibility with earlier
DSI systems, the capability of generating and interpreting this EoTp
can be enabled or disabled.
