From 9db115e231a665e82429ea63e2efda4abd4390fe Mon Sep 17 00:00:00 2001 From: Wolfgang Birkner Date: Tue, 15 Jul 2025 16:13:10 +0200 Subject: [PATCH] ARM: dts: imx6ulz-bsh-smm-m2: fix resume via console Despite the current configuration being compliant with the technical reference manual (TRM), testing on the system showed that resuming from suspend via UART4 (used as the console) fails unless any other UART is also enabled. In our use case, UART2 is enabled to ensure reliable resume when UART4 is used as the console.
