This is already required...
The original reg only include the DW HDMI controller registers:
reg = <0x200a0000 0x20000>;
But for now, I need to pass the external HDMI PHY registers:
reg = <0x200a0000 0x20000>, <0x12030000 0x10000>;

Does this change apply to rk3288 or just rk3229? If the latter, you
should make that clear. The driver needs to allow for old dtb's that
only have 1 clock.
It's the latter one, driver have allowed that by judging the device type,
but I should make the document more clear.
Based on Philipp's feedback, you also need to add a phys property.
Yes, I'm preparing the new patches that create a new separate phy
driver for external HDMI phy, there would be much difference from
this version.
Thanks for your respond,
