Hi Mark Cc Bard, Pierre-Louis, Jerome, DT-ML
This is v5 patch-set.
Current ASoC is supporting CPU/Codec = N:M (N < M) connection by using ch_map idea. This patch-set expands it that all connection uses this idea, and no longer N < M limit [1][2].

This patch is tested on Audio-Graph-Card2 with sample dtsi, but needs Tested-by, at least from Intel.
[PATCH 1/5] patch got Tested-by from Pierre-Louis / Jerome before, but v5 is using different idea from v4. Thus I didn't add below tag.

v4 -> v5 - use cpu/codec index on ch_maps - separate card2 sample DT patch into prepare and new feature - ch-maps -> ch-map-idx on DT
v3 -> v4 - add Jerome on To - add "description" on "ch-maps"
v2 -> v3 - tidyup comment - use more clear connection image on DT - "ch_maps" -> "ch-maps" on DT - Add DT maintainer on "To:" for all patches
v1 -> v2 - makes CPU/Codec connection relation clear on comment/sample - fixup type "connction" -> "connection" - makes error message clear
