Hi Bryan,
Thanks for making the changes. I only have some minor nitpicks now:

Nitpick: Please put no-map last for consistency.

This is now unused and overlaps with the definitions below so I'd just
drop it like in msm8916.dtsi.

s4_p1/p2 are specified twice, is this on purpose or accidental?

Please add
hnp-disable;
srp-disable;
adp-disable;
here for consistency with msm8916.dtsi. These are needed for correct
behavior if you enable CONFIG_USB_OTG_FSM, see commit bfd5d21abcd5c
("arm64: dts: qcom: msm8916: Move common USB properties to msm8916.dtsi")

This node needs to be reordered now, it should be below a53pll_c0.

and this node should be below usb/above intc (ordered by address).
