From 8e44ac61abaae56fc6eb537a04ed78b458c5b984 Mon Sep 17 00:00:00 2001 From: Hong Guan Date: Mon, 7 Jul 2025 11:55:13 -0500 Subject: [PATCH] arm64: dts: ti: k3-am62a7-sk: fix pinmux for main_uart1 main_uart1 reserved for TIFS firmware traces is routed to the onboard FT4232 via a FET switch which is connected to pin A21 and B21 of the SoC and not E17 and C17. Fix it.
