1 | Fixed Voltage regulators | ||
2 | |||
3 | Required properties: | ||
4 | - compatible: Must be "regulator-fixed"; | ||
5 | |||
6 | Optional properties: | ||
7 | - gpio: gpio to use for enable control | ||
8 | - startup-delay-us: startup time in microseconds | ||
9 | - enable-active-high: Polarity of GPIO is Active high | ||
10 | If this property is missing, the default assumed is Active low. | ||
11 | |||
12 | Any property defined as part of the core regulator | ||
13 | binding, defined in regulator.txt, can also be used. | ||
14 | However a fixed voltage regulator is expected to have the | ||
15 | regulator-min-microvolt and regulator-max-microvolt | ||
16 | to be the same. | ||
17 | |||
18 | Example: | ||
19 | |||
20 | abc: fixedregulator@0 { | ||
21 | compatible = "regulator-fixed"; | ||
22 | regulator-name = "fixed-supply"; | ||
23 | regulator-min-microvolt = <1800000>; | ||
24 | regulator-max-microvolt = <1800000>; | ||
25 | gpio = <&gpio1 16 0>; | ||
26 | startup-delay-us = <70000>; | ||
27 | enable-active-high; | ||

1 | Voltage/Current Regulators | ||
2 | |||
3 | Optional 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 | |||
14 | Example: | ||
15 | |||
16 | xyzreg: regulator@0 { | ||
17 | regulator-min-microvolt = <1000000>; | ||
18 | regulator-max-microvolt = <2500000>; | ||

22 | |||
23 | Regulator Consumers: | ||
24 | Consumer nodes can reference one or more of its supplies/ | ||
25 | regulators using the below bindings. | ||
26 | |||
27 | - <name>-supply: phandle to the regulator node | ||
28 | |||
29 | These are the same bindings that a regulator in the above | ||
30 | example used to reference its own supply, in which case | ||
31 | its just seen as a special case of a regulator being a | ||
32 | consumer itself. | ||
33 | |||
34 | Example of a consumer device node (mmc) referencing two | ||
35 | regulators (twl_reg1 and twl_reg2), | ||
36 | |||
37 | twl_reg1: regulator@0 { | ||
38 | ... | ||
39 | ... | ||
40 | ... | ||
