[PATCH v2 5/8] PCI: qcom: Add support for SA8540P

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

 



The SA8540P platform has five PCIe controllers: two 4-lane, two 2-lane
and one 1-lane.

Add a new "qcom,pcie-sa8540p" compatible string and reuse the 1.9.0 ops.

Note that like for SC8280XP, the SA8540P controllers need two or three
interconnect clocks to be enabled.
