From 7cf2fa8096414be4161f0dad8515ddf2ad3fc0f4 Mon Sep 17 00:00:00 2001 From: Bryan Brattlof Date: Fri, 29 Dec 2023 11:47:06 -0600 Subject: [PATCH] arm: dts: k3-am654: remove duplicate timer timer1 is really just the mcu_timer0 node redefined for the WKUP SPL. Remove the timer1 and replace it with the mcu_timer0 from the Linux device tree we imported into U-Boot.
