[PATCH 0/6] Add PCIe EP support for SDX65

[Rohit Agarwal]

Hi,

This series adds the devicetree support for PCIe PHY and PCIe EP on SDX65.
The PCIe EP is enabled on SDX65 MTP board.

Thanks,
Rohit.

The indentation here seems incorrect. The kernel uses 8-wide tabs.

Please turn this into a vertical list, like this:

No underscores in node names, pinctrl children node names
must end in -state. Please check your patches against

mux {} / config {} is unnecessary. You can simply do:

{
    pins = "gpio56";
    function = "pcie_clkreq";
    drive-strength = <2>;
    bias-disable;
};
