Subject: [PATCH v4 09/10] snd: dmaengine-pcm: add snd_dmaengine_pcm_get_quirks interface
Date: Sun, 6 Sep 2015 09:13:16 +0800 [thread overview]
Message-ID: <1441501996-14075-1-git-send-email-shawn.lin@rock-chips.com> (raw)
In-Reply-To: <1441501881-13700-1-git-send-email-shawn.lin@rock-chips.com>
Add snd_dmaengine_pcm_get_quirks for I2S devices to query
dma controller's quirks if they need it to make special workaround
due to broken dma controller design
