1 Cirrus Logic CS4271 DT bindings
3 This driver supports both the I2C and the SPI bus.
5 Required properties:
7 - compatible: "cirrus,cs4271"
9 For required properties on SPI, please consult
10 Documentation/devicetree/bindings/spi/spi-bus.txt
12 Required properties on I2C:
14 - reg: the i2c address
17 Optional properties:
19 - reset-gpio: a GPIO spec to define which pin is connected to the chip's
20 !RESET pin
21 - cirrus,amuteb-eq-bmutec: When given, the Codec's AMUTEB=BMUTEC flag
22 is enabled.
24 Examples:
26 codec_i2c: cs4271@10 {
27 compatible = "cirrus,cs4271";
28 reg = <0x10>;
29 reset-gpio = <&gpio 23 0>;
30 };
32 codec_spi: cs4271@0 {
33 compatible = "cirrus,cs4271";
34 reg = <0x0>;
35 reset-gpio = <&gpio 23 0>;
36 spi-max-frequency = <6000000>;
37 };
