Subject: [PATCH v1 1/2] dt-bindings: regulator: nxp,pca9450: document input supplies
Date: Mon, 27 Oct 2025 13:44:14 +0100 [thread overview]
Message-ID: <20251027124415.989301-2-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20251027124415.989301-1-o.rempel@pengutronix.de>
Add missing supply properties for PCA945x input pin groups:
- inl1-supply (for LDOs)
- inb13-supply (for BUCK1/3)
- inb26-supply (for BUCK2/6)
- inb45-supply (for BUCK4/5)
These properties describe external power sources for each input group.
