ACPI? NAK.
There are no cases of 'ltr' for DT, so fix ACPI.
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
Hence, add 'ltr' as a deprecated vendor prefix which would suppress the
following warning in case the compatible string used in ltrf216a driver
is "ltr,ltrf216a"
