-Subject: [PATCH 40/54] ASoC: BCM2708: Add 24 bit support
-
-This adds 24 bit support to the I2S driver of the BCM2708.
-Besides enabling the 24 bit flags, it includes two bug fixes:
-
-MMAP is not supported. Claiming this leads to strange issues
-when the format of driver and file do not match.
-
-The datasheet states that the width extension bit should be set
-for widths greater than 24, but greater or equal would be correct.
-This follows from the definition of the width field.
-
-Signed-off-by: Florian Meier <florian.meier@koalo.de>
