It would be nice if these nodes where sorted alphabetically.

damn, ok

On other platforms we left status = okay on the mdp child node, as it's
pretty rare that you want mdss okay, but mdp disabled...

Sure, but this is quite unrelated to HDK

Is that so?

This is how the pcie_1_phy_aux_clk was documented on SM8550 and SM8650
and downstream uses the same clock-frequency.
