Just as a heads up, Yongqin (cc'ed) reported this patch (now upstream)
seems to be causing trouble on the db845c.

It seems like its removing support for the "qcom,sdm845-qusb2-phy"
compatible string, which is documented:
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/phy/qcom,qusb2-phy.yaml#n23

and already in use:
   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/boot/dts/qcom/sdm845.dtsi#n2389

Should this instead have been an addition of the "qcom,qusb2-v2-phy",
line instead of replacing "qcom,sdm845-qusb2-phy"?
