[PATCH] Input: silead - list all supported compatible strings in binding document

[PATCH] Input: silead - list all supported compatible strings in binding document

[Javier Martinez Canillas]

The driver contains compatible strings for different models, but the DT
binding doc only lists one of them. Add the remaining to the document.

"dt-bindings: input: ..." is preferred for the subject, but no need to 
respin just for that.

Can we document it in Documentation/devicetree/bindings/submitting-patches.txt?

I'm asking because is true that at the beginning we used "dt-bindings: foo" for
all DT bindings patches but then many (most?) maintainers started asking for the
subsystem subject line to be used for both drivers and DT bindings docs since
they would be merging both and also they could miss the DT bindings patches if
their subsystem prefix was not used.

Yes. Actually, I was thinking of adding the preferred prefixes to
MAINTAINERS. Then checkpatch.pl could check it perhaps.

I'd argue that most subsys maintainers don't (or they just change it
when applying). Mark B does the most. I'm not going to waste any time
arguing over it if folks want something different. I'm mainly trying
to get rid of subjects like "Documentation: devicetree: bindings:
Document the DT binding for foo-bar". :)

That would be great.

Yeah, I don't have a strong opinion. I just want an authoritative doc
so I can refer subsystems maintainers to when they argue that I should
use their subsystem prefix instead of "dt-bindings: foo: ..." :)
