Subject: [PATCH 3/9] ASoC: dwc: add quirk to override COMP_PARAM_1 register
Date: Fri,  8 Jan 2016 18:22:05 -0500	[thread overview]
Message-ID: <1452295331-28476-4-git-send-email-alexander.deucher@amd.com> (raw)
In-Reply-To: <1452295331-28476-1-git-send-email-alexander.deucher@amd.com>

From: Maruthi Srinivas Bayyavarapu <Maruthi.Bayyavarapu@amd.com>

DWC for capture in ACP 2.x IP reports playback and capture capabilities
though it supports only capture. Added a quirk to override default value
to represent capture capability only.
