Subject: [PATCH 1/7] power: supply: axp20x_ac_power: Allow offlining
Date: Thu, 2 Jan 2020 00:36:27 -0600 [thread overview]
Message-ID: <20200102063633.65388-1-samuel@sholland.org> (raw)
AXP803/AXP813 have a flag that enables/disables the AC power supply
input. Allow control of this flag via the ONLINE property on those
variants.
