From 29ff4bbff793334d6aff2238fdc3ccf3859d60da Mon Sep 17 00:00:00 2001 From: Nicolas Frattaroli Date: Sat, 21 Jun 2025 16:37:55 +0200 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.
