From 182bef863cc37a9a387ae9bc0f1b05243234bd4a Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 26 Jun 2014 08:09:24 +0300 Subject: [PATCH] ASoC: davinci-mcasp: Fix S24_LE and U24_LE support 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).
