Hi Rob,
Yes, we understand there are no cases of 'ltr', but we have released devices which uses this string for probing the ltrf216a light sensor driver ( x86 with DT )
If we don't document this in vendor-prefixes.yaml, then the following warning is generated.
WARNING: DT compatible string vendor "ltr" appears un-documented -- check ./Documentation/devicetree/bindings/vendor-prefixes.yaml 364: FILE: drivers/iio/light/ltrf216a.c:313: + { .compatible = "ltr,ltrf216a" },
Can you suggest us what would be the right way to fix this warning if not documenting in vendor-prefixes.yaml?
Thanks, Shreeya Patel
