Example:
dais = <&i2s1_8ch>, <&pdm>;
capture,channel-mapping = <2 4>;
playback,channel-mapping = <2 0>;
The pdm has no playback channel. It cannot be set as master_chan.

Since the interrupt status of FUSB302 is R/C scheme, the interrupt
may miss between the top half and the bottom half (work), so make
the irq work to run with real time priority and get scheduled in time.

This is used, for example, when there are several multiplexers
on the same bus and the devices on the underlying buses might

The HDMI controller ignores the first FRAME_SYNC cycle data,
Lost one frame is no big deal for LPCM, but it does matter
for Bitstream (NLPCM/HBR), So, padding one frame before xfer
the real data to fix it.
Suggested to stop audio source before HDMI configure to make
sure audio data integrity on HDMI-PATH-ALWAYS-ON situation.

This patch introduce function always-on which allow controller
to keep clk (BCLK/SYNC) always-on.
In HDMI audio situation, we found some SINK devices need SOURCE
to keep xfer ACR, AUDS packet always on to fix sound compatibility.
And the AUDS packet is drived by audio source (e.g. I2S).

The pin range from GPIO0_B4 to GPIO0_D7 for rk3588 SoCs should set two
registers for iomux, since each of them has 8 bits width.
This patch fixes a issue when reset the iomux from a value from larger
than 8 to a value littler than 8, the high 4 bits should be reset to
'0'.

GMSL2 serializers include a novel line-fault detection circuit that
detects and reports open-circuit, short-to-battery, short-to-ground,
and line-to-line short. The line-fault monitor is disabled by default,
and configuration options are available through registers. Its status
can be read by register.
