From 73454c85cd91e8d0d43318c4110fcaf3ec4a6e33 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Wed, 21 Feb 2024 14:39:30 -0300 Subject: [PATCH] imx53-qsb: Convert to watchdog driver model Commit 68dcbdd594d4 ("ARM: imx: Add weak default reset_cpu()") caused the 'reset' command in U-Boot to not cause a board reset. Fix it by switching to the watchdog driver model via sysreset, which is the preferred method for implementing the watchdog reset.
