Subject: [PATCH V4 7/7] power: supply: rk817-charger: Clear full charge cal on resume
Date: Wed, 11 Nov 2026 14:56:27 -0600	[thread overview]
Message-ID: <20261111205627.56652-8-macroalpha82@gmail.com> (raw)
In-Reply-To: <20261111205627.56652-1-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.
