Subject: [PATCH] dt-bindings: pinctrl: renesas: Allow power-source
Date: Mon, 21 Sep 2026 18:25:50 -0500 [thread overview]
Message-ID: <20260921232551.3129244-1-robh@kernel.org> (raw)
RZ/V2M pin configuration nodes describe the I/O voltage with
power-source. Add the property and allow the 1800 mV and 3300 mV
values used by the DTS.
Assisted-by: LLM
