To modify hdmi default output color depth, use following dts:
&hdmi {
rockchip,defaultdepth = <10>;
}
rockchip,defaultdepth could be following value:
<0> auto select color depth, prefer 8bit
<8> 8bit
<10> 10bit

Use following command:
echo mode=<value> > /sys/class/display/HDMI/mode
<value> is decimal digits, lower 8bit is color mode, upper 8bit is depth.
For example:
value = 131 = 0x83 means YCbCr444 8bit output
value = 164 = 0xa4 means YCbCr422 10bit output
value = 0 means restore auto mode(8bit, priority YCbCr444)

If output tmdsclk is out of sink max tmds clk, we need to set output
mode to 8bit or YCbCr422.
For example, sink max tmds clk is 600M, but 3840x2160p-60 10bit tmdsclk
is 594*1.25 > 600, we set output mode to YCbCr422 10bit which tmds clk
is 594, so we can get max picture quality.

HDR is introduced by HDMI2.0a, which need parsing HDR Static
Metedata data Block defined in EDID, and send Dynamic Range
and Mastering InfoFrame to inform TV to switch to HDR mode.
If TV support HDR, it's EOTF is shown in sysfs node
/sys/class/display/HDMI/color with key word "Supported EOTF:".
For example, "Support EOTF: 0x7" means support following EOTF:
BIT0: Traditional gamma - SDR
BIT1: Traditional gamma - HDR
BIT2: ST_2084
To switch eotf mode, you can use following command:
echo eotf=value > /sys/class/display/HDMI/color
value could be:
0 - Disable sending Dynamic Range and Mastering InfoFrame
1 - Traditional gamma - SDR
2 - Traditional gamma - HDR
4 - ST_2084
0、1 both means SDR mode， 4 is HDR10/Dolby HDR mode.

If not, hdmi has been power up in uboot, should not operate phy
