Dear Rob,


Thank you very much for your reply and reminder.

I executed the following two inspection commands. I overlooked checking 
the yaml file, and I'm very sorry for that.
make O=$OUTKNL dt_binding_check DT_SCHEMA_FILES=arm/cix.yaml
make O=$OUTKNL CHECK_DTBS=y W=1 cix/sky1-orion-o6.dtb

After the release of v6.17 RC1, I will resubmit the patch.

Best regards,
Hans
