[PATCH v6 3/4] arm64: dts: qcom: sdm845-oneplus: Implement panel sleep pinctrl

From: David Heidelberg via B4 Relay
Date: Mon Nov 03 2025 - 06:49:20 EST


From: David Heidelberg <david@xxxxxxx>

We can DSI pin from 8mA to 2mA while suspend, do it.

In theory, should give us extra 2 hours of idle battery life.

cosmetic: sort pinctrl properties.
