X-Git-Tag: v6.6.17~3959^2^2~142^2~11
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=12547730e5b7c41e2203003cda74f39f43739c53;p=platform%2Fkernel%2Flinux-rpi.git

ASoC: SOF: Intel: hda-dai-ops: add/select DMA ops for SSP

The DMA widget ops are almost similar to the HDaudio ones, with the
exception of codec_dai_set_hext_stream() which is not relevant and the
format calculation which isn't dependent on the codec dai.

The DMA ops can be selected only starting with ACE_2_0.
