Subject: [PATCH v2 2/2] dt-bindings: hwmon: lm90: do not require VCC supply
Date: Mon, 20 Sep 2021 20:19:13 +0200	[thread overview]
Message-ID: <20210920181913.338772-2-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20210920181913.338772-1-krzysztof.kozlowski@canonical.com>

The LM90-like sensors usually need VCC supply, however this can be
hard-wired to the board main supply (like in SiFive HiFive Unmatched
RISC-V board).  Original bindings made VCC supply as required but in
practice several other boards skipped it.  Make it optional.
