Subject: [PATCH v2 1/4] power: supply: add charge_behaviour attributes
Date: Wed, 24 Nov 2021 00:27:01 +0100 [thread overview]
Message-ID: <20211123232704.25394-2-linux@weissschuh.net> (raw)
In-Reply-To: <20211123232704.25394-1-linux@weissschuh.net>
This a revised version of
"[RFC] add standardized attributes for force_discharge and inhibit_charge" [0],
incorporating discussion results.
The biggest change is the switch from two boolean attributes to a single
enum attribute.
