| Cirrus Logic CS4271 DT bindings |
| |
| This driver supports both the I2C and the SPI bus. |
| |
| Required properties: |
| |
| - compatible: "cirrus,cs4271" |
| |
| For required properties on SPI, please consult |
| Documentation/devicetree/bindings/spi/spi-bus.txt |
| |
| Required properties on I2C: |
| |
| - reg: the i2c address |
| |
| |
| Optional properties: |
| |
| - reset-gpio: a GPIO spec to define which pin is connected to the chip's |
| !RESET pin |
| - cirrus,amuteb-eq-bmutec: When given, the Codec's AMUTEB=BMUTEC flag |
| is enabled. |
| |
| Examples: |
| |
| codec_i2c: cs4271@10 { |
| compatible = "cirrus,cs4271"; |
| reg = <0x10>; |
| reset-gpio = <&gpio 23 0>; |
| }; |
| |
| codec_spi: cs4271@0 { |
| compatible = "cirrus,cs4271"; |
| reg = <0x0>; |
| reset-gpio = <&gpio 23 0>; |
| spi-max-frequency = <6000000>; |
| }; |
