Subject: [PATCH 1/3] dt-bindings: input: sun4i-lradc-keys: Add R329 and D1 compatibles
Date: Tue,  7 Sep 2021 22:40:14 -0500	[thread overview]
Message-ID: <20210908034016.24119-2-samuel@sholland.org> (raw)
In-Reply-To: <20210908034016.24119-1-samuel@sholland.org>

The R329 and D1 SoCs each contain an LRADC with a programming interface
compatible to earlier LRADCs. However, the LRADC now has its own clock
gate and reset line, instead of being always active.

To support this, add clock/reset properties to the binding, and require
them for the variant in the new SoCs.
