[PATCH v7 0/5] ASoC: makes CPU/Codec channel connection map more generic

[Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>]

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
