+Texas Instruments - tlv320dac33 Codec module
+
+The tlv320dac33 serial control bus communicates through I2C protocols.
+
+Required properties:
+
+- compatible - "ti,tlv320dac33"
+- reg - I2C slave address
+
+Optional properties:
+
+- reset-gpios - gpio pin to power the device, active low
+
+- interrupts - The interrupt output from the device.
+- interrupt-parent - The parent interrupt controller.
+
+- ti,keep-bclk - Keep the BCLK running in FIFO modes
+- ti,burst-bclkdiv - BCLK divider value in burst mode
+
+Example:
+
+tlv320dac33: audio-codec at 19 {
+ compatible = "ti,tlv320dac33";
+ reg = <0x19>;
+
+ interrupt-parent = <&gpio2>;
+ interrupts = <21 1>; /* gpio_53, IRQF_TRIGGER_RISING */
+ reset-gpios = <&gpio2 28 0>; /* gpio_60 */
+
+ ti,keep-bclk;
+ ti,burst-bclkdiv = <3>;
+};
