From b51600c01979ab1d1c4df17e8910696547ffb9a2 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 31 Aug 2013 13:43:36 +0100 Subject: [PATCH] ASoC: kirkwood-dma: remove IEC958_SUBFRAME formats The Audio block does not support IEC958 subframes as formatted by ALSA: they're very close, but not close enough. The formats differ by: 3 2 2 2 1 1 1 8 4 0 6 2 8 4 0 PCUVDDDDDDDDDDDDDDDD....AAAATTTT - IEC958 subframe PCUV0000........DDDDDDDDDDDDDDDD - Audio block format Where P = parity, C = channel status, U = user data, V = validity, D = sample data, A = aux, T = preamble. As can be seen, the position of the sample is in a different position, and the audio block does not have the aux or preamble bits.
