Subject: [PATCH 2/2] ASoC: dt-bindings: rt5645: add cbj sleeve gpio property
Date: Mon, 8 Apr 2024 17:10:57 +0800 [thread overview]
Message-ID: <20240408091057.14165-2-derek.fang@realtek.com> (raw)
In-Reply-To: <20240408091057.14165-1-derek.fang@realtek.com>
From: Derek Fang <derek.fang@realtek.com>
Add an optional gpio property to control external CBJ circuits
to avoid some electric noise caused by sleeve/ring2 contacts floating.
