From: Ben Gardiner Date: Wed, 18 May 2011 13:27:45 +0000 (-0400) Subject: ASoC: davinci-mcasp: enable ping-pong SRAM buffers X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=a0c8326397262f1817ee6c5212ad6adf43e3df36;p=openwrt%2Fstaging%2Fblogic.git ASoC: davinci-mcasp: enable ping-pong SRAM buffers The davinci-i2s driver copies the platform data for playback and capture sram sizes which is in turn used by davinci-pcm to allocate ping-pong buffers. Copy also the platform data in davinci-mcasp probe.
