+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
space before tab ^
+- ti,burst-bclkdiv - BCLK divider value in burst mode
What are valid values? What's the default?
+Example:
+tlv320dac33: audio-codec@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>;
+};
