Subject: [PATCH] ASoC: dwc: Extends DW_I2S_QUIRK_COMP_PARAM1 to playback
Date: Fri, 16 Feb 2018 13:11:15 +0530	[thread overview]
Message-ID: <1518766875-15164-4-git-send-email-akshu.agrawal@amd.com> (raw)
In-Reply-To: <1518766875-15164-1-git-send-email-akshu.agrawal@amd.com>

When we have same register to tell capture and playback capability
of a device and we want separate cpu dais for playback and
capture. Then, DW_I2S_QUIRK_COMP_PARAM1 is used to enable one
capability per dai.
