Subject: [PATCH AUTOSEL 5.15 03/15] ASoC: dt-bindings: rt5645: add cbj sleeve gpio property
Date: Tue,  7 May 2024 19:13:12 -0400	[thread overview]
Message-ID: <20240507231333.394765-3-sashal@kernel.org> (raw)
In-Reply-To: <20240507231333.394765-1-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.
