From 2782f48a8677913f299542cbeda2371764a9376c Mon Sep 17 00:00:00 2001 From: Ondrej Jirman Date: Sat, 27 Aug 2022 20:50:43 +0200 Subject: [PATCH 297/487] power: supply: axp20x-battery: Enable poweron by RTC alarm For the Pinephone to be able to poweron on RTC alarm, some bits in PMIC need to be enabled. This will cause PMIC to be wakeable by SoC pulling the interrupt line low. This may need some coordination from a bootloader.
