Subject: [alsa-devel] [PATCH AUTOSEL 4.19 215/219] ASoC: rt5645: Headphone Jack sense inverts on the LattePanda board
Date: Fri, 22 Nov 2019 00:49:06 -0500 [thread overview]
Message-ID: <20191122054911.1750-207-sashal@kernel.org> (raw)
In-Reply-To: <20191122054911.1750-1-sashal@kernel.org>
From: Hui Wang <hui.wang@canonical.com>
[ Upstream commit 406dcbc55a0a20fd155be889a4a0c4b812f7c18e ]
The LattePanda board has a sound card chtrt5645, when there is nothing
plugged in the headphone jack, the system thinks the headphone is
plugged in, while we plug a headphone in the jack, the system thinks
the headphone is unplugged.
If adding quirk=0x21 in the module parameter, the headphone jack can
work well. So let us fix it via platform_data.
