Subject: [PATCH] power: supply: cw2015: Add CHARGE_NOW support
Date: Thu, 18 Feb 2021 07:42:50 -0500	[thread overview]
Message-ID: <20210218124250.128008-1-martin@ashbysoft.com> (raw)

CHARGE_NOW is expected by some user software (such as waybar)
instead of 'CAPACITY', in order to correctly calculate remaining battery
life.
