[PATCH v5 0/3] ASoC: dt-bindings: audio-graph-card: switch to yaml base Documentation

[Kuninori Morimoto]

Hi Rob, Mark
Cc: Sameer

These are v5 of switch to yaml base Documentation for
audio-graph-card and renesas,rsnd which uses audio-graph-card.

v4 -> v5
	- move "endpoint" under "port"

v3 -> v4
	- fixuped yamllint warnings/errors

v2 -> v3
	- fixuped Rob's pointed points

v1 -> v2
	- upgrade dt-schema, and fixup errors for [2/2] patch

Kuninori Morimoto (3):
  dt-bindings: ASoC: audio-graph-card: switch to yaml base Documentation
  dt-bindings: ASoC: renesas,rsnd: switch to yaml base Documentation
  dt-bindings: ASoC: renesas,rsnd: Add r8a77961 support

-Audio Graph Card:
-
-Audio Graph Card specifies audio DAI connections of SoC <-> codec.
-It is based on common bindings for device graphs.
-see ${LINUX}/Documentation/devicetree/bindings/graph.txt
-
-Basically, Audio Graph Card property is same as Simple Card.
-see ${LINUX}/Documentation/devicetree/bindings/sound/simple-card.yaml
-
-Below are same as Simple-Card.

How'd that sneak in? Can we drop or at least mark deprecated? There's 
not any users in upstream dts files.

[PATCH v5 2/3] dt-bindings: ASoC: renesas,rsnd: switch to yaml base Documentation

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

This patch switches from .txt base to .yaml base Document.
It is still keeping detail explanations at .txt
