[PATCH v2 10/13] arm64: dts: qcom: sm8150: switch PCIe QMP PHY to new style of bindings

Mon Jul 31 03:57:56 PDT 2023


Change the PCIe QMP PHY to use newer style of QMP PHY bindings (single
resource region, no per-PHY subnodes). As a part of this conversion also
add the missing "ref" clock to the PCIe PHY devices.
