Configures the boost 14*4882a593Smuzhiyun converter's output voltage in mV. The range is from VP to 8V with 15*4882a593Smuzhiyun increments of 100mV. 16*4882a593Smuzhiyun 17*4882a593Smuzhiyun - cirrus,boost-nanohenry: Inductor value for boost converter. The value is 18*4882a593Smuzhiyun in nH and they can be values of 1000nH, 1100nH, 1200nH, 1500nH, and 2200nH. 19*4882a593Smuzhiyun 20*4882a593SmuzhiyunOptional properties: 21*4882a593Smuzhiyun 22*4882a593Smuzhiyun - reset-gpios: GPIO used to reset the amplifier. 23*4882a593Smuzhiyun 24*4882a593Smuzhiyun - interrupts : IRQ line info CS35L34. 25*4882a593Smuzhiyun (See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt 26*4882a593Smuzhiyun for further information relating to interrupt properties) 27*4882a593Smuzhiyun 28*4882a593Smuzhiyun - cirrus,boost-peak-milliamp : Boost converter peak current limit in mA. The 29*4882a593Smuzhiyun range starts at 1200mA and goes to a maximum of 3840mA with increments of 30*4882a593Smuzhiyun 80mA. The default value is 2480mA. 31*4882a593Smuzhiyun 32*4882a593Smuzhiyun - cirrus,i2s-sdinloc : ADSP SDIN I2S channel location. Indicates whether the 33*4882a593Smuzhiyun received mono data is in the left or right portion of the I2S frame 34*4882a593Smuzhiyun according to the AD0 pin or directly via this configuration. 35*4882a593Smuzhiyun 0x0 (Default) = Selected by AD0 input (if AD0 = LOW, use left channel), 36*4882a593Smuzhiyun 0x2 = Left, 37*4882a593Smuzhiyun 0x1 = Selected by the inversion of the AD0 input (if AD0 = LOW, use right 38*4882a593Smuzhiyun channel), 39*4882a593Smuzhiyun 0x3 = Right. 40*4882a593Smuzhiyun 41*4882a593Smuzhiyun - cirrus,gain-zc-disable: Boolean property. If set, the gain change will take 42*4882a593Smuzhiyun effect without waiting for a zero cross. 43*4882a593Smuzhiyun 44*4882a593Smuzhiyun - cirrus,tdm-rising-edge: Boolean property. If set, data is on the rising edge of 45*4882a593Smuzhiyun SCLK. Otherwise, data is on the falling edge of SCLK. 46*4882a593Smuzhiyun 47*4882a593Smuzhiyun 48*4882a593SmuzhiyunExample: 49*4882a593Smuzhiyun 50*4882a593Smuzhiyuncs35l34: cs35l34@40 { 51*4882a593Smuzhiyun compatible = "cirrus,cs35l34"; 52*4882a593Smuzhiyun reg = <0x40>; 53*4882a593Smuzhiyun 54*4882a593Smuzhiyun interrupt-parent = <&gpio8>; 55*4882a593Smuzhiyun interrupts = <3 IRQ_TYPE_LEVEL_LOW>; 56*4882a593Smuzhiyun 57*4882a593Smuzhiyun reset-gpios = <&gpio 10 0>; 58*4882a593Smuzhiyun 59*4882a593Smuzhiyun cirrus,boost-vtge-milltvolt = <8000>; /* 8V */ 60*4882a593Smuzhiyun cirrus,boost-ind-nanohenry = <1000>; /* 1uH */ 61*4882a593Smuzhiyun cirrus,boost-peak-milliamp = <3000>; /* 3A */ 62*4882a593Smuzhiyun}; 63
