From 0d03a557eb57016592944ea4ea8cc712501d36e4 Mon Sep 17 00:00:00 2001 From: Andrej Picej Date: Wed, 19 Jul 2023 13:43:27 +0200 Subject: [PATCH] ARM: dts: imx6: pfla02: Rely on PMIC reboot/reset handler MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Due to the missing signal connection between i.MX6 WDOG_B pin and the PMICs external reset, the internal i.MX6 watchdog is not able to reset the phyFLEX SoM properly. Thus disable the internal i.MX6 watchdog to prevent unexpected PMIC settings after reset. NOTE: This patch should not be backported as it might break existing uses and fixes in bootloaders.
