BU18TL82-M supports MIPI DSI and LVDS data
transmission by ROHM's original CDR (Clock Data
Recovery) technology. This chip is the serial interface
transmitter IC of the Clockless Link-BD series.
BU18TL82-M converts the MIPI DSI and LVDS data
stream into Clockless Link format transmit through 2
pairs of differential wires.
BU18RL82-M supports LVDS data transmission by
ROHM's original CDR (Clock Data Recovery) technology.
This chip is serial interface receiver IC of the Clockless
Link-BD series.
BU18RL82-M converts Clockless link stream into a
LVDS format, and transmits through one or two ports of
LVDS.
Flexible Input / Output mode is suitable for a variety of
application interface.

For linestate irq as a wakeup source, we need to reconfigure the
linestate filter value base on 32KHz clk at suspend time, and restore
it to the default when the system resume.
By the way, set the grf to handle the phy status when the system
suspend, which can support the linestate wakeup even the PD of the
USB controller was off for RK3588 OTG1 port.

This patch add uevent to notify the application layer how much ppm
is different between USB clk and AUDIO clk.
The event include two parts USB_STATE and PPM. For example:
g_audio_work: sent uac uevent USB_STATE=SET_AUDIO_CLK PPM=12
g_audio_work: sent uac uevent USB_STATE=SET_AUDIO_CLK PPM=-1
Note: The ppm compensation depends on the method implement of
clk drift and compensation in the audio driver (eg. sound/soc/
rockchip/rockchip_i2s.c). So if you want the ppm compensation to
take effect, please make sure the related driver has implemented.

When the request pixelclk is under 600MHz, vop2 will
calculate dclk first. When the dsc is enabled. vop2 will
calculate dsc clk first then dclk. the dclk rate get from
the first time calclulate dsc clk and second set dck may
be different, which will get wrong dsc clk when use the
latest dclk rate to recalculate it. So the dclk should
be calculated before dsc clk when dsc enable and pixelclk
is under 600MHz.

1. Always enable pre-emphasis in SOF & EOP & chirp & non-chirp state;
2. Set Tx HS pre_emphasize strength to 3'b010;
3. Set 45ohm HS ODT value to 5'b10111 for better Rx ODT resistance.
