From a4c707f56bcaa6d6eb9cfcbefa7f7f5e16d6cf6b Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Fri, 9 Aug 2024 12:12:47 -0300 Subject: [PATCH] tqma6q_mba6: 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.
