power: supply: ab8500: Exit maintenance if too low voltage

2022-06-09T20:10:05+00:00

The maintenance charging is supposedly designed such that the maintenance current compensates for the battery discharge curve, and as the charging progress from CC/CV -> maintenance A -> maintenance B states, we end up on a reasonable voltage to restart ordinary CC/CV charging after the safety timer at the maintenance B state exits. However: old batteries discharge quicker, and in an old battery we might not get to the expiration of the maintenance B timer before the battery is completely depleted and the system powers off with an empty battery. This is hardly the desire of anyone leaving their phone in the charger for a few days! Introduce a second clause in both maintenance states such that we exit the state and return to ordinary CC/CV charging if the voltage drops below charge_restart_voltage_uv or 95% if this is not defined for the battery.

power: supply: ab8500: Respect charge_restart_voltage_uv

2022-06-09T20:09:58+00:00

The battery info contains a voltage indicating when the voltage is so low that it is time to restart the CC/CV charging. Make the AB8500 respect and prioritize this setting over the hardcoded 95% threshold. Break out the check into its own function and add some safeguards so we do not run into unpredictable side effects.

power: supply: cros_peripheral: Use struct_size() helper in kzalloc()

2022-06-09T20:03:27+00:00

Similar to the handling of cros_usbpd_charger_ec_command in commit 441d38c60fbe ("power: supply: cros_usbpd: Use struct_size() helper in kzalloc()"), we thought a patch might be needed here as well. Make use of the struct_size() helper instead of an open-coded version, in order to avoid any potential type mistakes or integer overflows that, in the worst scenario, could lead to heap overflows.
