Now, we want to create new board, and then, we want to use below codec if exist. Can you show it to us if it was exist ? (I researched it on upstream Linux source tree, but couldn't find....)
- upstream Linux supports its driver
- it supports TDM format
- it supports 5.1ch sound
- it supports DT bindings (if possible)
Some of the Wolfson/Cirrus mobile CODECs can do that with some fiddling and mixing of output types but they're not really a good fit. Most of the things doing 5.1 are like the WM8580 - they use separate data lines rather than TDM, as far as I can tell a lot of 5.1 systems out there do this by hooking up multiple stereo CODECs in parallel as slaves rather than by using a single 5.1 CODEC.
