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>;

It's the latter one, driver have allowed that by judging the device type,
but I should make the document more clear.

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,
