We can configurate phy setting in dts node "rockchip,phy_table"
with following format:
<maxfreq pre-emphasis slopeboost clklevel data0level data1level data2level>
Phy setting table must list from low freq to high freq and cover
all supported frequency, for example:
&hdmi {
status = "okay";
rockchip,phy_table =
<165000000 0 0 17 17 17 17>,
<340000000 0 0 14 17 17 17>,
<594000000 0 0 9 17 17 17>;
};
If dts node is not exist, we use default setting defined in code.
