[PATCH v2 02/11] dt-bindings: pci: qcom: Document PCIe bindings for SM8450

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

 



Document the PCIe DT bindings for SM8450 SoC. The PCIe IP is similar
to the one used on SM8250, however unlike SM8250, PCIe0 and PCIe1 use
different set of clocks, so two compatible entries are required.
