+Subject: [PATCH 212/752] ASoC: davinci-evm: Add device tree binding
+
+Device tree support for Davinci Machine driver
+
+When the board boots with device tree, the driver will receive card,
+codec, dai interface details (like the card name, DAPM routing map,
+phandle for the audio components described in the dts file, codec mclk
+speed). The card will be set up based on this information. Since the
+routing is provided via DT we can mark the card fully routed so core
+can take care of disconnecting the unused pins.

++* Texas Instruments SoC audio setups with TLV320AIC3X Codec
++
++Required properties:
++- compatible : "ti,da830-evm-audio" : forDM365/DA8xx/OMAPL1x/AM33xx
++- ti,model : The user-visible name of this sound complex.
++- ti,audio-codec : The phandle of the TLV320AIC3x audio codec
++- ti,mcasp-controller : The phandle of the McASP controller
++- ti,codec-clock-rate : The Codec Clock rate (in Hz) applied to the Codec
++- ti,audio-routing : 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 for sources and
++  sinks are the codec's pins, and the jacks on the board:
++
++  TLV320AIC3X pins:
++
++  * LLOUT
++  * RLOUT
++  * MONO_LOUT
++  * HPLOUT
++  * HPROUT
++  * HPLCOM
++  * HPRCOM
++  * MIC3L
++  * MIC3R
++  * LINE1L
++  * LINE2L
++  * LINE1R
++  * LINE2R
++
++  Board connectors:
++
++  * Headphone Jack
++  * Line Out
++  * Mic Jack
++  * Line In
++
++
++Example:
++
++sound {
++	compatible = "ti,da830-evm-audio";
++	ti,model = "DA830 EVM";
++	ti,audio-codec = <&tlv320aic3x>;
++	ti,mcasp-controller = <&mcasp1>;
++	ti,codec-clock-rate = <12000000>;
++	ti,audio-routing =
++		"Headphone Jack",       "HPLOUT",
++		"Headphone Jack",       "HPROUT",
++		"Line Out",             "LLOUT",
++		"Line Out",             "RLOUT",
++		"MIC3L",                "Mic Bias 2V",
++		"MIC3R",                "Mic Bias 2V",
++		"Mic Bias 2V",          "Mic Jack",
++		"LINE1L",               "Line In",
++		"LINE2L",               "Line In",
++		"LINE1R",               "Line In",
++		"LINE2R",               "Line In";
