Subject: [PATCH V4 5/7] power: supply: rk817-charger: Expose boot voltage and OCV values
Date: Wed, 11 Nov 2026 14:56:25 -0600	[thread overview]
Message-ID: <20261111205627.56652-6-macroalpha82@gmail.com> (raw)
In-Reply-To: <20261111205627.56652-1-macroalpha82@gmail.com>

From: Chris Morgan <macromorgan@hotmail.com>

Expose PWRON_VOL as POWER_SUPPLY_PROP_VOLTAGE_BOOT and the current
rested pair as POWER_SUPPLY_PROP_VOLTAGE_OCV. The OCV value will
return -ENODATA while the battery is not resting.
