[PATCH] arm64: dts: qcom: sc8280xp-x13s: Add RTC support
From: Abel Vesa
Date: Fri Dec 30 2022 - 03:59:13 EST
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.
