I'm slightly in favor of not introducing the enum. You'd have to fix the indentation
if you wanted to introduce it anyway [1] (checkpatch there also seems to complain about
the commit hash for the Fixes tag but that looks like a spurious warning to me since
df7c4a8c1b47 is in Linus' tree [2]):
yamllint warnings/errors:
./Documentation/devicetree/bindings/i2c/apple,i2c.yaml:25:9: [warning] wrong indentation: expected 10 but found 8 (indentation)
Best,
Sven
