+OMAP3 HA (HEAD acoustics) audio controller
+
+Required properties:
+- compatible: "ha,ha-dsp-card" for OMAP3-HA board (TAO3530 based)
+- ti,model: Name of the sound card (for example "omap3-ha")
+- ti,mcbsp: phandle for the McBSP node
+- ti,codec: phandle for the twl4030 audio node
+- gpios: GPIO used to sync the clock for playback and record
+
+Optional properties:
+- ha_dsp_codec_slave:
+ Add this property to test the codec in slave mode or without actual codec.
+ This makes it possible to test this driver by letting the OMAP be the DAI
+ link master.
+
+Example:
+sound2 {
+ compatible = "ha,ha-dsp-card";
+ ti,model = "omap3-ha";
+
+ /* McBSP3 is used for HA-DSP */
+ ti,mcbsp = <&mcbsp3>;
+ ti,codec = <&soc_audio>;
+
+ /* GPIO to sync the clock for playback and record */
+ gpios = <&gpio2 12 GPIO_ACTIVE_LOW>; /* GPIO 44 */
+};
