[PATCH 2/3] arm64: dts: rockchip: enable internal pull-up on PCIE_WAKE# for RK3399 Puma

From: Quentin Schulz
Date: Fri Mar 08 2024 - 07:53:10 EST


From: Quentin Schulz <quentin.schulz@xxxxxxxxxxxxxxxxxxxxx>

The PCIE_WAKE# has a diode used as a level-shifter, and is used as an
input pin. The SoC default for this pin is a pull-up, which is correct
but the pinconf in the introducing commit missed that, so let's fix this
oversight.
