Subject: [PATCH 1/4] checks: tigthen up nr-gpios prop exception
Date: Mon,  3 May 2021 20:59:41 -0700	[thread overview]
Message-ID: <20210504035944.8453-2-ilya.lipnitskiy@gmail.com> (raw)
In-Reply-To: <20210504035944.8453-1-ilya.lipnitskiy-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

There are no instances of nr-gpio in the Linux kernel tree, only
"[<vendor>,]nr-gpios", so make the check stricter.

nr-gpios without a "vendor," prefix is also invalid, according to the DT
spec[0], and there are no DT files in the Linux kernel tree with
non-vendor nr-gpios. There are some drivers, but they are not DT spec
compliant, so don't suppress the check for them.
