[PATCH 1/6] dt-bindings: phy: qcom,sc8280xp-qmp-pcie-phy: Add qcs8300 16 GT/s PHY

From: Krishna Chaitanya Chundru

Date: Mon Sep 21 2026 - 07:06:43 EST


The QCS8300 16 GT/s x4 QMP PCIe PHY was previously described using only
the qcom,sa8775p-qmp-gen4x4-pcie-phy compatible, since no QCS8300-specific
compatible existed for this PHY. This was a mistake, as it left the PHY
undocumented as QCS8300 hardware and indistinguishable from SA8775P in
the binding.

Correct this by documenting a dedicated
"qcom,qcs8300-qmp-gen4x4-pcie-phy" compatible, with
"qcom,sa8775p-qmp-gen4x4-pcie-phy" listed as its fallback compatible.
