This node is not in the right place. Up through v8, this lived inside
reserved-memory. Here it seems to apply into the clocks {} node, which
is not the right spot.

Should any of the *-supply regulators be specified? Or are they all
board specific? Or just not needed? The example has these:
vdd-0.8-cx-mx-supply = <&pm8998_l5>;
vdd-1.8-xo-supply = <&vreg_l7a_1p8>;
vdd-1.3-rfa-supply = <&vreg_l17a_1p3>;
vdd-3.3-ch0-supply = <&vreg_l25a_3p3>;

Thanks for spotting this. This was a rebase problem.
I will post the next patchset by fixing this.

These votes are optional and were required for older targets.
We do not need these proxy votes in host now.
