Subject: arch: arm: dts: k3-am62a7-phyboard-lyra: Disable unused watchdogs in U-Boot
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=dfd185939d9e4dc89e4365b142a14ffd7e775854;p=thirdparty%2Fu-boot.git

arch: arm: dts: k3-am62a7-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.
