Subject: [PATCH] dt-bindings: mfd: Ensure 'syscon' has a more specific compatible
Date: Wed, 10 Jun 2020 13:46:25 -0600	[thread overview]
Message-ID: <20200610194625.3597460-1-robh@kernel.org> (raw)

Using 'syscon' alone should be avoided as compatible strings should be
specific enough to identify the exact set of registers contained. Update
the schema to ensure at least 2 compatible strings are present.

FYI, there's 43 cases of this on arm32 in my testing.
