Subject: [PATCH] ASoC: dt-bindings: qcom,sdm845: convert to dtschema
Convert the Samsung SDM845 sound card bindings to DT schema.
Changes during conversion: do not require 'codec' under dai-links - not
present in all nodes of examples and DTS; not required by the driver.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

-* Qualcomm Technologies Inc. SDM845 ASoC sound card driver
-
-This binding describes the SDM845 sound card, which uses qdsp for audio.
-
-- compatible:
- Usage: required
- Value type: <stringlist>
- Definition: must be one of this
- "qcom,sdm845-sndcard"
- "qcom,db845c-sndcard"
- "lenovo,yoga-c630-sndcard"
-
-- audio-routing:
- Usage: Optional
- Value type: <stringlist>
- Definition: A list of the connections between audio components.
- Each entry is a pair of strings, the first being the
- connection's sink, the second being the connection's
- source. Valid names could be power supplies, MicBias
- of codec and the jacks on the board.
-
-- model:
- Usage: required
- Value type: <stringlist>
- Definition: The user-visible name of this sound card.
-
-- aux-devs
- Usage: optional
- Value type: <array of phandles>
- Definition: A list of phandles for auxiliary devices (e.g. analog
- amplifiers) that do not appear directly within the DAI
- links. Should be connected to another audio component
- using "audio-routing".
-
-= dailinks
-Each subnode of sndcard represents either a dailink, and subnodes of each
-dailinks would be cpu/codec/platform dais.
-
-- link-name:
- Usage: required
- Value type: <string>
- Definition: User friendly name for dai link
-
-= CPU, PLATFORM, CODEC dais subnodes
-- cpu:
- Usage: required
- Value type: <subnode>
- Definition: cpu dai sub-node
-
-- codec:
- Usage: required
- Value type: <subnode>
- Definition: codec dai sub-node
-
-- platform:
- Usage: Optional
- Value type: <subnode>
- Definition: platform dai sub-node
-
-- sound-dai:
- Usage: required
- Value type: <phandle>
- Definition: dai phandle/s and port of CPU/CODEC/PLATFORM node.
-
-Example:
-
-audio {
- compatible = "qcom,sdm845-sndcard";
