-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>;
