Subject: [PATCH 3/3] docs: ABI: charge_control_end_threshold may not support all values
Date: Sun, 28 Aug 2022 21:29:20 +0200 [thread overview]
Message-ID: <20220828192920.805253-4-lkml@vorpal.se> (raw)
In-Reply-To: <20220828192920.805253-1-lkml@vorpal.se>
Some laptops (for example Toshiba Satellite Z830) only supports some fixed
values. Allow for this and document the expected behaviour in such cases.
Wording suggested by Hans de Goede.
