[PATCH] arm64: dts: rockchip: Fix PCIe v3 pinctrl for BPI-R2-Pro
From: David Heidelberg via B4 Relay
Date: Sun Mar 01 2026 - 10:57:13 EST
From: David Heidelberg <david@xxxxxxx>
Add missing pinctrl for PD4 (PI6C PCIe clock enable,
PCIE_CLKEN_H_GPIO0_D4) and set output high.
This does fix freeze at initialization due pinctrl being in input
state.
