1Voltage/Current Regulators 2 3Optional properties: 4- regulator-name: A string used as a descriptive name for regulator outputs 5- regulator-min-microvolt: smallest voltage consumers may set 6- regulator-max-microvolt: largest voltage consumers may set 7- regulator-microvolt-offset: Offset applied to voltages to compensate for voltage drops 8- regulator-min-microamp: smallest current consumers may set 9- regulator-max-microamp: largest current consumers may set 10- regulator-always-on: boolean, regulator should never be disabled 11- regulator-boot-on: bootloader/firmware enabled regulator 12- <name>-supply: phandle to the parent supply/regulator node 13- regulator-ramp-delay: ramp delay for regulator(in uV/uS) 14 15Deprecated properties: 16- regulator-compatible: If a regulator chip contains multiple 17 regulators, and if the chip's binding contains a child node that 18 describes each regulator, then this property indicates which regulator 19 this child node is intended to configure. If this property is missing, 20 the node's name will be used instead. 21 22Example: 23 24 xyzreg: regulator@0 { 25 regulator-min-microvolt = <1000000>; 26 regulator-max-microvolt = <2500000>; 27 regulator-always-on; 28 vin-supply = <&vin>; 29 }; 30 31Regulator Consumers: 32Consumer nodes can reference one or more of its supplies/ 33regulators using the below bindings. 34 35- <name>-supply: phandle to the regulator node 36 37These are the same bindings that a regulator in the above 38example used to reference its own supply, in which case 39its just seen as a special case of a regulator being a 40consumer itself. 41 42Example of a consumer device node (mmc) referencing two 43regulators (twl_reg1 and twl_reg2), 44 45 twl_reg1: regulator@0 { 46 ... 47 ... 48 ... 49 }; 50 51 twl_reg2: regulator@1 { 52 ... 53 ... 54 ... 55 }; 56 57 mmc: mmc@0x0 { 58 ... 59 ... 60 vmmc-supply = <&twl_reg1>; 61 vmmcaux-supply = <&twl_reg2>; 62 }; 63
