From ebf9f13938c0710fc830c755b788115572d09527 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Thu, 22 Jan 2026 23:14:21 +0100 Subject: [PATCH] lantiq: AVM Fritz 736x: fix PCIe reset GPIO The vr9.dtsi configures the GPIO 38 as reset GPIO. Also the fon LED is configured on GPIO 38. This conflicts and makes the probing of the PCIe controller fail in OpenWrt 25.12. The AVM GPL source code configured GPIO 21 as PCIe reset.
