Subject: [PATCH] arm64: dts: rockchip: enable PCIe on ROCK 4D
|
|
|
|
The RADXA ROCK 4D board has a PCIe controller connected to a flat flex
|
|
connector, compatible with the one the RPi5 uses.
|
|
|
|
Enable the associated combphy and pcie controller node, as well as add
|
|
the remaining pinctrl definition for the reset.
