GCC_HDMI_CLKREF_CLK is a child of xo, so you can drop the latter.
It would also be worth confirming whether it's really powering the
PHY and not the TX.. You can test that by trying to only power on the
phy (e.g. call the phy_power_on or whatever APIs) with and without the
clock
I'd prefer to keep it. I think the original DT used one of LN_BB clocks
here, so it might be that the HDMI uses CXO2 / LN_BB instead of the main
CXO.
If somebody can check, which clock is actually used for the HDMI, it
would be really great.
+CC jhugo - could you please take a look?

Documentation is not great but it looks like CXO from what little I can
find.
