1 Sandbox, PMIC regulators
3 This device uses two drivers:
4 - drivers/power/pmic/sandbox.c (as parent I/O device)
5 - drivers/power/regulator/sandbox.c (for child regulators)
7 This file describes the binding info for the REGULATOR driver.
9 First, please read the binding info for the PMIC:
10 - doc/device-tree-bindings/pmic/sandbox.txt
16 The sandbox PMIC can support: ldo1, ldo2, buck1, buck2.
18 For each PMIC's regulator subnode, there is one required property:
19 - regulator-name: used for regulator uclass platform data '.name'
22 - regulator-min-microvolt: minimum allowed Voltage to set
23 - regulator-max-microvolt: minimum allowed Voltage to set
24 - regulator-min-microamps: minimum allowed Current limit to set (LDO1/BUCK1)
25 - regulator-max-microamps: minimum allowed Current limit to set (LDO1/BUCK1)
26 - regulator-always-on: regulator should be never disabled
27 - regulator-boot-on: regulator should be enabled by the bootloader
29 Example PMIC's regulator subnodes:
32 regulator-name = "VDD_1.0V";
33 regulator-min-microvolt = <1000000>;
34 regulator-max-microvolt = <1200000>;
35 regulator-min-microamps = <100000>;
36 regulator-max-microamps = <400000>;
41 regulator-name = "VDD_1.8V";
42 regulator-min-microvolt = <1800000>;
43 regulator-max-microvolt = <1800000>;
