Subject: [PATCH v3] ASoC: dt-bindings: qcom,sm8250: add SDM845 sound

The Qualcomm SDM845 sound card bindings are almost the same as SM8250,
except "pin-switches" and "widgets" properties.  These were not
documented in SDM845 text bindings but are actually valid for SDM845.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
Reviewed-by: Stephan Gerhold <stephan@...hold.net>

Changes since v2:
1. Add missing Lenovo and db845c compatibles (Stephan).

Changes since v1:
1. Integrate into SM8250 instead of creating new file (Stephan).

-* 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.
