Re: [linux-sunxi] [PATCH v2 2/9] power: supply: axp20x_ac_power: Fix reporting online status

AXP803/AXP813 have a flag that enables/disables the AC power supply input. This flag does not affect the status bits in PWR_INPUT_STATUS. Its effect can be verified by checking the battery charge/discharge state (bit 2 of PWR_INPUT_STATUS), or by examining the current draw on the AC input.

Take this flag into account when getting the ONLINE property of the AC input, on PMICs where this flag is present.
