Drop PCIE_AUX_CLK from the PCIe PHY nodes of Qcom SoCs

[PATCH 01/14] dt-bindings: phy: qcom,ipq8074-qmp-pcie: Drop PCIE_AUX_CLK from pcie_phy node

Posted by Manivannan Sadhasivam 1 year, 11 months ago

PCIe PHY hw doesn't require PCIE_AUX_CLK for functioning. This clock is
only required by the PCIe controller. Hence drop it from the binding.
