These are not readable like this... Required properties: - compatible: "cirrus,cs35l32" - reg: the I2C address of the device for I2C. Address is determined by the level of the AD0 pin. Level 0 is 0x40 while Level 1 is 0x41. - VA-supply,VP-supply: power supplies for the device, as covered in Documentation/devicetree/bindings/regulator/regulator.txt. Optional properties: - reset-gpios: a GPIO spec for the reset pin. If specified, it will be deasserted before communication to the codec starts. - cirrus,boost-manager:Boost voltage control. 0 = Automatically managed. Boost-converter output voltage is the higher of the two: Class G or adaptive LED voltage. 1 = Automatically managed irrespective of audio, adapting for low-power ...... > +Example: > + > +codec: codec@40 { > + compatible = "cirrus,cs35l32"; > + reg = <0x40>; > + reset-gpios = <&gpio 10 0>; > + cirrus,boost-manager = <0x03>; > + cirrus,sdout-datacfg = <0x02>; > + VA-supply = <®_audio>; > +}; -- Regards, Varka Bhadram. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
