5 by the prefix of regulator node's name, or, if this fails, by the prefix of the
6 regulator's "regulator-name" property. Usually the pmic I/O driver will provide
13 For the node name e.g.: "prefix[:alpha:]num { ... }":
14 - the driver prefix should be: "prefix" - case sensitive
15 - the node name's "num" is set as "dev->driver_data" on bind
17 Example the prefix "ldo" will pass for: "ldo1", "ldo@1", "ldoreg@1, ...
19 Binding by means of the node's name is preferred. However if the node names
21 can't or do not want to change them then binding against the "regulator-name"
22 property is possible. The syntax for the prefix of the "regulator-name" property
23 is the same as the one for the regulator's node name.
26 named "BOOST_DRV". Using prefix "regualtor@1" for driver matching would load
27 the same driver for both regulators, hence the prefix is ambiguous.
30 - regulator-name: a string, required by the regulator uclass, used for driver
31                   binding if binding by node's name prefix fails
32 - regulator-min-microvolt: a minimum allowed Voltage value
33 - regulator-max-microvolt: a maximum allowed Voltage value
34 - regulator-min-microamp: a minimum allowed Current value
35 - regulator-max-microamp: a maximum allowed Current value
36 - regulator-always-on: regulator should never be disabled
37 - regulator-boot-on: enabled by bootloader/firmware
38 - regulator-ramp-delay: ramp delay for regulator (in uV/us)
41 The "regulator-name" constraint is used for setting the device's uclass
42 platform data '.name' field. And the regulator device name is set from
43 it's node name. If "regulator-name" is not provided in dts, node name
44 is chosen for setting the device's uclass platform data '.name' field.
46 Other kernel-style properties, are currently not used.
50 - regulator-min-microvolt is equal to regulator-max-microvolt
51 - regulator-min-microamp is equal to regulator-max-microamp
52 - regulator-always-on or regulator-boot-on is set
