[PATCH] arm64: dts: qcom: sc8280xp-x13s: Add RTC support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The PMK8350 PMIC has an available RTC block. Describe it in
sc8280xp-pmics dtsi and enable it in Lenovo Thinkpad X13s specific dts.
Mark it as wakeup-source to allow waking the system from sleep.
