Subject: [PATCH AUTOSEL 6.8 10/52] ASoC: dt-bindings: rt5645: add cbj sleeve gpio property
Date: Tue, 7 May 2024 19:06:36 -0400 [thread overview]
Message-ID: <20240507230800.392128-10-sashal@kernel.org> (raw)
In-Reply-To: <20240507230800.392128-1-sashal@kernel.org>
From: Derek Fang <derek.fang@realtek.com>
[ Upstream commit 306b38e3fa727d22454a148a364123709e356600 ]
Add an optional gpio property to control external CBJ circuits
to avoid some electric noise caused by sleeve/ring2 contacts floating.
