From b17c594ac499c8cfb91093d62ff83d90a547ecf1 Mon Sep 17 00:00:00 2001 From: Wadim Egorov Date: Wed, 30 Jul 2025 17:42:11 +0200 Subject: [PATCH] arch: arm: dts: k3-am625-phyboard-lyra: Disable unused watchdogs in U-Boot The watchdog driver probes all available watchdog devices. This causes SMP boot errors when bringing up secondary CPUs. In our setup, only a single watchdog is needed to monitor the boot process until userspace or the OS takes over. Disable all unnecessary watchdog devices in U-Boot to avoid conflicts during CPU bring-up.
