[PATCH v2 3/7] dt-bindings: PCI: qcom: Add IPQ9574 PCIe controller

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



IPQ9574 has PCIe controllers which are almost identical to IPQ6018.
The only difference is that the "iface" clock is not required.
Document this difference along with the compatible string.
