1*4882a593Smuzhiyun* TPS65086 Power Management Integrated Circuit (PMIC) bindings 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunRequired properties: 4*4882a593Smuzhiyun - compatible : Should be "ti,tps65086". 5*4882a593Smuzhiyun - reg : I2C slave address. 6*4882a593Smuzhiyun - interrupts : The interrupt line the device is connected to. 7*4882a593Smuzhiyun - interrupt-controller : Marks the device node as an interrupt controller. 8*4882a593Smuzhiyun - #interrupt-cells : The number of cells to describe an IRQ, should be 2. 9*4882a593Smuzhiyun The first cell is the IRQ number. 10*4882a593Smuzhiyun The second cell is the flags, encoded as trigger 11*4882a593Smuzhiyun masks from ../interrupt-controller/interrupts.txt. 12*4882a593Smuzhiyun - gpio-controller : Marks the device node as a GPIO Controller. 13*4882a593Smuzhiyun - #gpio-cells : Should be two. The first cell is the pin number and 14*4882a593Smuzhiyun the second cell is used to specify flags. 15*4882a593Smuzhiyun See ../gpio/gpio.txt for more information. 16*4882a593Smuzhiyun - regulators: : List of child nodes that specify the regulator 17*4882a593Smuzhiyun initialization data. Child nodes must be named 18*4882a593Smuzhiyun after their hardware counterparts: buck[1-6], 19*4882a593Smuzhiyun ldoa[1-3], swa1, swb[1-2], and vtt. Each child 20*4882a593Smuzhiyun node is defined using the standard binding for 21*4882a593Smuzhiyun regulators and the optional regulator properties 22*4882a593Smuzhiyun defined below. 23*4882a593Smuzhiyun 24*4882a593SmuzhiyunOptional regulator properties: 25*4882a593Smuzhiyun - ti,regulator-step-size-25mv : This is applicable for buck[1-6], set this 26*4882a593Smuzhiyun if the regulator is factory set with a 25mv 27*4882a593Smuzhiyun step voltage mapping. 28*4882a593Smuzhiyun - ti,regulator-decay : This is applicable for buck[1-6], set this if 29*4882a593Smuzhiyun the output needs to decay, default is for 30*4882a593Smuzhiyun the output to slew down. 31*4882a593Smuzhiyun 32*4882a593SmuzhiyunExample: 33*4882a593Smuzhiyun 34*4882a593Smuzhiyun pmic: tps65086@5e { 35*4882a593Smuzhiyun compatible = "ti,tps65086"; 36*4882a593Smuzhiyun reg = <0x5e>; 37*4882a593Smuzhiyun interrupt-parent = <&gpio1>; 38*4882a593Smuzhiyun interrupts = <28 IRQ_TYPE_LEVEL_LOW>; 39*4882a593Smuzhiyun interrupt-controller; 40*4882a593Smuzhiyun #interrupt-cells = <2>; 41*4882a593Smuzhiyun gpio-controller; 42*4882a593Smuzhiyun #gpio-cells = <2>; 43*4882a593Smuzhiyun 44*4882a593Smuzhiyun regulators { 45*4882a593Smuzhiyun buck1 { 46*4882a593Smuzhiyun regulator-name = "vcc1"; 47*4882a593Smuzhiyun regulator-min-microvolt = <1600000>; 48*4882a593Smuzhiyun regulator-max-microvolt = <1600000>; 49*4882a593Smuzhiyun regulator-boot-on; 50*4882a593Smuzhiyun ti,regulator-decay; 51*4882a593Smuzhiyun ti,regulator-step-size-25mv; 52*4882a593Smuzhiyun }; 53*4882a593Smuzhiyun }; 54*4882a593Smuzhiyun }; 55
