Jan,

As part of my final sanity checks, I noticed that we missed this: is a checkpatch warning

WARNING: DT compatible string "rohm,dh2228fv" appears un-documented -- check ./Documentation/devicetree/bindings/
#629: FILE: arch/arm64/boot/dts/ti/k3-am65-iot2050-common.dtsi:581:
compatible = "rohm,dh2228fv";

I cannot pick up nodes that are'nt documented as yaml in
Documentation/devicetree

I know this is irritating to find such nodes that already have previous
users and the person coming last gets to deal with "new rules".. but
sorry for catching this so late.

Here are the options that come to mind:

option 1) - drop the node and resubmit.

option 2) - get the documentation into linux master tree and then submit
the patches.


I think we should just drop the node and resubmit - since this is a more
intrusive change and I don't have your platform handy, I am going to
suggest you make a call :(

Additionally please install yamlint and dtbs_schema -> run dtbs_check. I
see more than a few warnings there which may need some closer look.


A full log against linux-next is here: https://pastebin.ubuntu.com/p/qR69h28c5f/


PS: https://github.com/nmenon/kernel_patch_verify/blob/master/kpv

I have been using my script to verify with kpv -C -V -n num_patches and
then digging through the logs.
