Subject: [PATCH V2 4/4] power: supply: rk817-charger: Clear full charge cal on resume
Date: Mon, 2 Nov 2026 08:39:42 -0600 [thread overview]
Message-ID: <20261102143942.305293-5-macroalpha82@gmail.com> (raw)
In-Reply-To: <20261102143942.305293-1-macroalpha82@gmail.com>
From: Chris Morgan <macromorgan@hotmail.com>
After suspending, the coulumb counter may be off by a bit. Set the
cal_soc bit to 0 so that the gauge may be recalibrated again on a
full charge.
