+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

+
+	interrupt-parent = <&gpio2>;
