Subject: [PATCH v3 1/5] dt-bindings: qcom: lpass-lpi-common: add reserved GPIOs property
Date: Fri, 27 Mar 2026 22:10:32 -0400 [thread overview]
Message-ID: <20260328021036.85945-2-mailingradian@gmail.com> (raw)
In-Reply-To: <20260328021036.85945-1-mailingradian@gmail.com>
There can be reserved GPIOs on the LPASS LPI pin controller to possibly
control sensors. Add the property for reserved GPIOs so they can be
avoided appropriately.
Adapted from the same entry in qcom,tlmm-common.yaml.
