Subject: [PATCH] arm64: dts: qcom: qcs6490-rb3gen2: enable PMIC Volume and Power buttons
Date: Wed, 20 Mar 2024 17:40:16 +0530 [thread overview]
Message-ID: <20240320121016.2878367-1-quic_uchheda@quicinc.com> (raw)
The Volume Down & Power buttons are controlled by the PMIC via
the PON hardware, and the Volume Up is connected to a PMIC gpio.
Enable the necessary hardware and setup the GPIO state for the
Volume Up gpio key.
