ASoC: rsnd: don't use PDTA bit for 24bit on SSI
Current SSI uses PDTA bit which indicates data that Input/Output data are Right-Aligned. But, 24bit sound should be Left-Aligned in this HW. Because Linux is using Right-Aligned data, and HW uses Left-Aligned data, current 24bit data is missing lower 8bit. To fix this issue, this patch removes PDTA bit, and shift 8bit in necessary module Reported-by: Hiroyuki Yokoyama <hiroyuki.yokoyama.vx@renesas.com> Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by: Hiroyuki Yokoyama <hiroyuki.yokoyama.vx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
