Subject: [PATCH 227/389] 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.
