1*4882a593SmuzhiyunTPS65132 regulators 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunRequired properties: 4*4882a593Smuzhiyun- compatible: "ti,tps65132" 5*4882a593Smuzhiyun- reg: I2C slave address 6*4882a593Smuzhiyun 7*4882a593SmuzhiyunOptional Subnode: 8*4882a593SmuzhiyunDevice supports two regulators OUTP and OUTN. A sub node within the 9*4882a593Smuzhiyun device node describe the properties of these regulators. The sub-node 10*4882a593Smuzhiyun names must be as follows: 11*4882a593Smuzhiyun -For regulator outp, the sub node name should be "outp". 12*4882a593Smuzhiyun -For regulator outn, the sub node name should be "outn". 13*4882a593Smuzhiyun 14*4882a593Smuzhiyun-enable-gpios:(active high, output) Regulators are controlled by the input pins. 15*4882a593Smuzhiyun If it is connected to GPIO through host system then provide the 16*4882a593Smuzhiyun gpio number as per gpio.txt. 17*4882a593Smuzhiyun-active-discharge-gpios: (active high, output) Some configurations use delay mechanisms 18*4882a593Smuzhiyun on the enable pin, to keep the regulator enabled for some time after 19*4882a593Smuzhiyun the enable signal goes low. This GPIO is used to actively discharge 20*4882a593Smuzhiyun the delay mechanism. Requires specification of ti,active-discharge-time-us 21*4882a593Smuzhiyun-ti,active-discharge-time-us: how long the active discharge gpio should be 22*4882a593Smuzhiyun asserted for during active discharge, in microseconds. 23*4882a593Smuzhiyun 24*4882a593SmuzhiyunEach regulator is defined using the standard binding for regulators. 25*4882a593Smuzhiyun 26*4882a593SmuzhiyunExample: 27*4882a593Smuzhiyun 28*4882a593Smuzhiyun tps65132@3e { 29*4882a593Smuzhiyun compatible = "ti,tps65132"; 30*4882a593Smuzhiyun reg = <0x3e>; 31*4882a593Smuzhiyun 32*4882a593Smuzhiyun outp { 33*4882a593Smuzhiyun regulator-name = "outp"; 34*4882a593Smuzhiyun regulator-boot-on; 35*4882a593Smuzhiyun regulator-always-on; 36*4882a593Smuzhiyun enable-gpios = <&gpio 23 0>; 37*4882a593Smuzhiyun }; 38*4882a593Smuzhiyun 39*4882a593Smuzhiyun outn { 40*4882a593Smuzhiyun regulator-name = "outn"; 41*4882a593Smuzhiyun regulator-boot-on; 42*4882a593Smuzhiyun regulator-always-on; 43*4882a593Smuzhiyun regulator-active-discharge = <0>; 44*4882a593Smuzhiyun enable-gpios = <&gpio 40 0>; 45*4882a593Smuzhiyun }; 46*4882a593Smuzhiyun }; 47
