1CS35L34 Speaker Amplifier 2 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 in 11 Documentation/devicetree/bindings/regulator/regulator.txt. 12 13 - cirrus,boost-vtge-millivolt : Boost Voltage Value. Configures the boost 14 converter's output voltage in mV. The range is from VP to 8V with 15 increments of 100mV. 16 17 - cirrus,boost-nanohenry: Inductor value for boost converter. The value is 18 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.txt 26 for further information relating to interrupt properties) 27 28 - cirrus,boost-peak-milliamp : Boost converter peak current limit in mA. The 29 range starts at 1200mA and goes to a maximum of 3840mA with increments of 30 80mA. The default value is 2480mA. 31 32 - cirrus,i2s-sdinloc : ADSP SDIN I2S channel location. Indicates whether the 33 received mono data is in the left or right portion of the I2S frame 34 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 right 38 channel), 39 0x3 = Right. 40 41 - cirrus,gain-zc-disable: Boolean property. If set, the gain change will take 42 effect without waiting for a zero cross. 43 44 - cirrus,tdm-rising-edge: Boolean property. If set, data is on the rising edge of 45 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
