Hi Mark Cc Bard, Pierre-Louis, Jerome, DT-ML
This is v7 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].

ASoC core code ([PATCH 1/5]) is same as v6 and it was tested by Pierre-Louis, and Jerome. Big change on v7 is basically for Audio-Graph-Card2.
v6 -> v7 - use "endpoint" for N:M connection instead of ch-map-idx on Audio-Graph-Card2
v5 -> v6 - tidyup some warnings - rename "ch-map-idx" -> "channel-map-index" - Update "channel-map-index" description - add Tested-by from Pierre-Louis / Jerome
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
Kuninori Morimoto (5): ASoC: makes CPU/Codec channel connection map more generic ASoC: audio-graph-card2: use better image for Multi connection ASoC: audio-graph-card2: add CPU:Codec = N:M support ASoC: audio-graph-card2-custom-sample: Add connection image ASoC: audio-graph-card2-custom-sample: add CPU/Codec = N:M sample
