regulator: Updates for v6.13
This was a quite quiet release for regulators on the drivers front, but
we do have two small but useful core improvements:
- Improve handling of cases where DT platforms specify both DT and
init_data based configuration for a single regulator.
- A helper of_regulator_get_optional() to simplify writing generic
bindings for regulator consumers in subsystems.
There's also some YAML conversions for the DT bindings which are a big
part of the diffstat.

Linear Technology LTC3676 8-output regulators
|
||||
|
||||
Required properties:
|
||||
- compatible: "lltc,ltc3676"
|
||||
- reg: I2C slave address
|
||||
|
||||
Required child node:
|
||||
- regulators: Contains eight regulator child nodes sw1, sw2, sw3, sw4,
|
||||
ldo1, ldo2, ldo3, and ldo4, specifying the initialization data as
|
||||
documented in Documentation/devicetree/bindings/regulator/regulator.txt.
|
||||
|
||||
Each regulator is defined using the standard binding for regulators. The
|
||||
nodes for sw1, sw2, sw3, sw4, ldo1, ldo2 and ldo4 additionally need to specify
|
||||
the resistor values of their external feedback voltage dividers:
|
||||
|
||||
Required properties (not on ldo3):
|
||||
- lltc,fb-voltage-divider: An array of two integers containing the resistor
|
||||
values R1 and R2 of the feedback voltage divider in ohms.
|
||||
|
||||
Regulators sw1, sw2, sw3, sw4 can regulate the feedback reference from:
|
||||
412.5mV to 800mV in 12.5 mV steps. The output voltage thus ranges between
|
||||
0.4125 * (1 + R1/R2) V and 0.8 * (1 + R1/R2) V.
|
||||
|
||||
Regulators ldo1, ldo2, and ldo4 have a fixed 0.725 V reference and thus output
|
||||
0.725 * (1 + R1/R2) V. The ldo3 regulator is fixed to 1.8 V. The ldo1 standby
|
||||
regulator can not be disabled and thus should have the regulator-always-on
|
||||
property set.

- regulator-min-microvolt : smallest voltage consumers may set

the control voltage needed to generate the corresponding

regulator-min/max-microvolt output voltage.
