From: Jeeja KP Date: Fri, 24 Mar 2017 17:40:25 +0000 (+0530) Subject: ASoC: Intel: Skylake: Use the sig_bits to define dai bps capability X-Git-Tag: v4.12-rc1~115^2^2~14^2~28 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7f975a385b9313a03c13fb0be0a129c626f9a54e;p=karo-tx-linux.git ASoC: Intel: Skylake: Use the sig_bits to define dai bps capability For calculating the HDA DMA format, use the max_bps supported by the DAI caps instead of fixing it to 32/24. For host DMA the Max bps support is 32, but in case of link DMA, this depends on the codec capability. So use the sig_bits to define the bps supported by dai.
