Subject: [PATCH] ASoC: davinci-mcasp: Fix S24_LE and U24_LE support
Date: Thu, 26 Jun 2014 08:09:24 +0300 [thread overview]
Message-ID: <1403759364-14524-1-git-send-email-peter.ujfalusi@ti.com> (raw)
In case of S24_LE/U24_LE modes we expect 24bits on the bus while the samples
are stored and transferred in memory on 32bits (lower 3 bytes of the 4
bytes).
