Jan, I was about to pick up the patches and was running through
my sanity checks and the following caught my eye with dtbs_check
(dtschema is at 2021.2.1) test against next-20210311

/workdir/arch/arm64/boot/dts/ti/k3-am654-base-board.dt.yaml: rti at 40610000: $nodename:0: 'rti at 40610000' does not match '^watchdog(@.*|-[0-9a-f])?$'

Please use watchdog at 40610000 instead of rti at 40610000

Since this is a minor change, I have done this change locally. let me
know if you have an issue and I can drop it off my branch for a new
version.
