Merge tag 'regulator-v5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator 

Pull regulator updates from Mark Brown:
 "The bulk of the standout changes in this release are cleanups, with
  the core work being a combination of factoring out common code into
  helpers and the completion of the conversion of the core to use GPIO
  descriptors.

  Summary:

   - Addition of helper functions for current limits and conversion of
     drivers to use them by Axel Lin.

   - Lots and lots of cleanups from Axel Lin.

   - Conversion of the core to use GPIO descriptors rather than numbers
     by Linus Walleij.

   - New drivers for Maxim MAX77650 and ROHM BD70528"

Optional properties:

- clock-output-names	: Should contain name for output clock.

- rohm,reset-snvs-powered : Transfer BD718x7 to SNVS state at reset.



The BD718x7 supports two different HW states as reset target states. States

are called as SNVS and READY. At READY state all the PMIC power outputs go

down and OTP is reload. At the SNVS state all other logic and external

devices apart from the SNVS power domain are shut off. Please refer to NXP

i.MX8 documentation for further information regarding SNVS state. When a

reset is done via SNVS state the PMIC OTP data is not reload. This causes

power outputs that have been under SW control to stay down when reset has

switched power state to SNVS. If reset is done via READY state the power

outputs will be returned to HW control by OTP loading. Thus the reset

target state is set to READY by default. If SNVS state is used the boot

crucial regulators must have the regulator-always-on and regulator-boot-on

properties set in regulator node.

Fixed Voltage regulators



Required properties:

- compatible: Must be "regulator-fixed";

- regulator-name: Defined in regulator.txt as optional, but required here.



Optional properties:

- gpio: gpio to use for enable control

- startup-delay-us: startup time in microseconds

- enable-active-high: Polarity of GPIO is Active high

If this property is missing, the default assumed is Active low.

- gpio-open-drain: GPIO is open drain type.

  If this property is missing then default assumption is false.

-vin-supply: Input supply name.



Any property defined as part of the core regulator

binding, defined in regulator.txt, can also be used.

However a fixed voltage regulator is expected to have the

regulator-min-microvolt and regulator-max-microvolt

to be the same.



Example:



	abc: fixedregulator@0 {

		compatible = "regulator-fixed";

		regulator-name = "fixed-supply";

		regulator-min-microvolt = <1800000>;

		regulator-max-microvolt = <1800000>;

		gpio = <&gpio1 16 0>;

		startup-delay-us = <70000>;

		enable-active-high;

		regulator-boot-on;

		gpio-open-drain;

		vin-supply = <&parent_reg>;

	};
