1CS35L34 Speaker Amplifier2 3Required properties:4 5 - compatible : "cirrus,cs35l34"6 7 - reg : the I2C address of the device for I2C.8 9 - VA-supply, VP-supply : power supplies for the device,10 as covered in11 Documentation/devicetree/bindings/regulator/regulator.txt.12 13 - cirrus,boost-vtge-millivolt : Boost Voltage Value. Configures the boost14 converter's output voltage in mV. The range is from VP to 8V with15 increments of 100mV.16 17 - cirrus,boost-nanohenry: Inductor value for boost converter. The value is18 in nH and they can be values of 1000nH, 1100nH, 1200nH, 1500nH, and 2200nH.19 20Optional properties:21 22 - reset-gpios: GPIO used to reset the amplifier.23 24 - interrupts : IRQ line info CS35L34.25 (See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt26 for further information relating to interrupt properties)27 28 - cirrus,boost-peak-milliamp : Boost converter peak current limit in mA. The29 range starts at 1200mA and goes to a maximum of 3840mA with increments of30 80mA. The default value is 2480mA.31 32 - cirrus,i2s-sdinloc : ADSP SDIN I2S channel location. Indicates whether the33 received mono data is in the left or right portion of the I2S frame34 according to the AD0 pin or directly via this configuration.35 0x0 (Default) = Selected by AD0 input (if AD0 = LOW, use left channel),36 0x2 = Left,37 0x1 = Selected by the inversion of the AD0 input (if AD0 = LOW, use right38 channel),39 0x3 = Right.40 41 - cirrus,gain-zc-disable: Boolean property. If set, the gain change will take42 effect without waiting for a zero cross.43 44 - cirrus,tdm-rising-edge: Boolean property. If set, data is on the rising edge of45 SCLK. Otherwise, data is on the falling edge of SCLK.46 47 48Example:49 50cs35l34: cs35l34@40 {51 compatible = "cirrus,cs35l34";52 reg = <0x40>;53 54 interrupt-parent = <&gpio8>;55 interrupts = <3 IRQ_TYPE_LEVEL_LOW>;56 57 reset-gpios = <&gpio 10 0>;58 59 cirrus,boost-vtge-milltvolt = <8000>; /* 8V */60 cirrus,boost-ind-nanohenry = <1000>; /* 1uH */61 cirrus,boost-peak-milliamp = <3000>; /* 3A */62};63
