Subject: [PATCH AUTOSEL 5.8 12/53] ALSA: hda/tegra: Program WAKEEN register for Tegra
Date: Mon, 7 Sep 2020 12:31:38 -0400 [thread overview]
Message-ID: <20200907163220.1280412-12-sashal@kernel.org> (raw)
In-Reply-To: <20200907163220.1280412-1-sashal@kernel.org>
From: Mohan Kumar <mkumard@nvidia.com>
[ Upstream commit 23d63a31d9f44d7daeac0d1fb65c6a73c70e5216 ]
The WAKEEN bits are used to indicate which bits in the
STATESTS register may cause wake event during the codec
state change request. Configure the WAKEEN register for
the Tegra to detect the wake events.
