Address is determined by the level 8*9cf44690SBrian Austin of the AD0 pin. Level 0 is 0x40 while Level 1 is 0x41. 9*9cf44690SBrian Austin 10*9cf44690SBrian Austin - VA-supply, VP-supply : power supplies for the device, 11*9cf44690SBrian Austin as covered in Documentation/devicetree/bindings/regulator/regulator.txt. 12*9cf44690SBrian Austin 13*9cf44690SBrian AustinOptional properties: 14*9cf44690SBrian Austin 15*9cf44690SBrian Austin - reset-gpios : a GPIO spec for the reset pin. If specified, it will be 16*9cf44690SBrian Austin deasserted before communication to the codec starts. 17*9cf44690SBrian Austin 18*9cf44690SBrian Austin - cirrus,boost-manager : Boost voltage control. 19*9cf44690SBrian Austin 0 = Automatically managed. Boost-converter output voltage is the higher 20*9cf44690SBrian Austin of the two: Class G or adaptive LED voltage. 21*9cf44690SBrian Austin 1 = Automatically managed irrespective of audio, adapting for low-power 22*9cf44690SBrian Austin dissipation when LEDs are ON, and operating in Fixed-Boost Bypass Mode 23*9cf44690SBrian Austin if LEDs are OFF (VBST = VP). 24*9cf44690SBrian Austin 2 = (Default) Boost voltage fixed in Bypass Mode (VBST = VP). 25*9cf44690SBrian Austin 3 = Boost voltage fixed at 5 V. 26*9cf44690SBrian Austin 27*9cf44690SBrian Austin - cirrus,sdout-datacfg : Data configuration for dual CS35L32 applications only. 28*9cf44690SBrian Austin Determines the data packed in a two-CS35L32 configuration. 29*9cf44690SBrian Austin 0 = Left/right channels VMON[11:0], IMON[11:0], VPMON[7:0]. 30*9cf44690SBrian Austin 1 = Left/right channels VMON[11:0], IMON[11:0], STATUS. 31*9cf44690SBrian Austin 2 = (Default) left/right channels VMON[15:0], IMON [15:0]. 32*9cf44690SBrian Austin 3 = Left/right channels VPMON[7:0], STATUS. 33*9cf44690SBrian Austin 34*9cf44690SBrian Austin - cirrus,sdout-share : SDOUT sharing. Determines whether one or two CS35L32 35*9cf44690SBrian Austin devices are on board sharing SDOUT. 36*9cf44690SBrian Austin 0 = (Default) One IC. 37*9cf44690SBrian Austin 1 = Two IC's. 38*9cf44690SBrian Austin 39*9cf44690SBrian Austin - cirrus,battery-recovery : Low battery nominal recovery threshold, rising VP. 40*9cf44690SBrian Austin 0 = 3.1V 41*9cf44690SBrian Austin 1 = 3.2V 42*9cf44690SBrian Austin 2 = 3.3V (Default) 43*9cf44690SBrian Austin 3 = 3.4V 44*9cf44690SBrian Austin 45*9cf44690SBrian Austin - cirrus,battery-threshold : Low battery nominal threshold, falling VP. 46*9cf44690SBrian Austin 0 = 3.1V 47*9cf44690SBrian Austin 1 = 3.2V 48*9cf44690SBrian Austin 2 = 3.3V 49*9cf44690SBrian Austin 3 = 3.4V (Default) 50*9cf44690SBrian Austin 4 = 3.5V 51*9cf44690SBrian Austin 5 = 3.6V 52*9cf44690SBrian Austin 53*9cf44690SBrian AustinExample: 54*9cf44690SBrian Austin 55*9cf44690SBrian Austincodec: codec@40 { 56*9cf44690SBrian Austin compatible = "cirrus,cs35l32"; 57*9cf44690SBrian Austin reg = <0x40>; 58*9cf44690SBrian Austin reset-gpios = <&gpio 10 0>; 59*9cf44690SBrian Austin cirrus,boost-manager = <0x03>; 60*9cf44690SBrian Austin cirrus,sdout-datacfg = <0x02>; 61*9cf44690SBrian Austin VA-supply = <®_audio>; 62*9cf44690SBrian Austin}; 63
