[v4,08/30] dt-bindings: phy: add qcom,msm8996-qmp-pcie-phy schema

Commit Message

Johan Hovold Aug. 30, 2022, 11:29 a.m. UTC

The QMP PHY DT schema is getting unwieldy. Break out the odd-bird
msm8996-qmp-pcie-phy which is the only QMP PHY that uses separate
"per-lane" nodes.

Add an example node based on a cleaned up version of msm8996.dtsi.
