1CS35L32 audio CODEC2 3Required properties:4 5 - compatible : "cirrus,cs35l32"6 7 - reg : the I2C address of the device for I2C. Address is determined by the level8 of the AD0 pin. Level 0 is 0x40 while Level 1 is 0x41.9 10 - VA-supply, VP-supply : power supplies for the device,11 as covered in Documentation/devicetree/bindings/regulator/regulator.txt.12 13Optional properties:14 15 - reset-gpios : a GPIO spec for the reset pin. If specified, it will be16 deasserted before communication to the codec starts.17 18 - cirrus,boost-manager : Boost voltage control.19 0 = Automatically managed. Boost-converter output voltage is the higher20 of the two: Class G or adaptive LED voltage.21 1 = Automatically managed irrespective of audio, adapting for low-power22 dissipation when LEDs are ON, and operating in Fixed-Boost Bypass Mode23 if LEDs are OFF (VBST = VP).24 2 = (Default) Boost voltage fixed in Bypass Mode (VBST = VP).25 3 = Boost voltage fixed at 5 V.26 27 - cirrus,sdout-datacfg : Data configuration for dual CS35L32 applications only.28 Determines the data packed in a two-CS35L32 configuration.29 0 = Left/right channels VMON[11:0], IMON[11:0], VPMON[7:0].30 1 = Left/right channels VMON[11:0], IMON[11:0], STATUS.31 2 = (Default) left/right channels VMON[15:0], IMON [15:0].32 3 = Left/right channels VPMON[7:0], STATUS.33 34 - cirrus,sdout-share : SDOUT sharing. Determines whether one or two CS35L3235 devices are on board sharing SDOUT.36 0 = (Default) One IC.37 1 = Two IC's.38 39 - cirrus,battery-recovery : Low battery nominal recovery threshold, rising VP.40 0 = 3.1V41 1 = 3.2V42 2 = 3.3V (Default)43 3 = 3.4V44 45 - cirrus,battery-threshold : Low battery nominal threshold, falling VP.46 0 = 3.1V47 1 = 3.2V48 2 = 3.3V49 3 = 3.4V (Default)50 4 = 3.5V51 5 = 3.6V52 53Example:54 55codec: codec@40 {56 compatible = "cirrus,cs35l32";57 reg = <0x40>;58 reset-gpios = <&gpio 10 0>;59 cirrus,boost-manager = <0x03>;60 cirrus,sdout-datacfg = <0x02>;61 VA-supply = <®_audio>;62};63
