Convert the bindings of Qualcomm SPMI regulators to DT schema.
Signed-off-by: Robert Marko <robimarko@xxxxxxxxx>
---
I am aware that syscon alone is not really acceptable, its converted
directly from the old text bindings.
There is also the issue of some MSM8994, MSM8996 and APQ8096 devices using
'#address-cells', '#size-cells', some even defining reg property for
regulators.
Any advice on how to solve these issues is appreciated.
Changes in v2:
* Remove the forgotten text bindings
* Move allOf after patternProperties
* Use my private email as the maintainer email

-The content of each sub-node is defined by the standard binding for regulators -
-see regulator.txt - with additional custom properties described below:
-
-- regulator-initial-mode:
- Usage: optional
- Value type: <u32>
- Description: 2 = Set initial mode to auto mode (automatically select
- between HPM and LPM); not available on boost type
- regulators.
-
- 1 = Set initial mode to high power mode (HPM), also referred
- to as NPM. HPM consumes more ground current than LPM, but
- it can source significantly higher load current. HPM is not
- available on boost type regulators. For voltage switch type
- regulators, HPM implies that over current protection and
- soft start are active all the time.
-
- 0 = Set initial mode to low power mode (LPM).
-
-- qcom,ocp-max-retries:
- Usage: optional
- Value type: <u32>
- Description: Maximum number of times to try toggling a voltage switch
- off and back on as a result of consecutive over current
- events.
-
-- qcom,ocp-retry-delay:
- Usage: optional
- Value type: <u32>
- Description: Time to delay in milliseconds between each voltage switch
- toggle after an over current event takes place.
-
-- qcom,pin-ctrl-enable:
- Usage: optional
- Value type: <u32>
- Description: Bit mask specifying which hardware pins should be used to
- enable the regulator, if any; supported bits are:
- 0 = ignore all hardware enable signals
- BIT(0) = follow HW0_EN signal
- BIT(1) = follow HW1_EN signal
- BIT(2) = follow HW2_EN signal
- BIT(3) = follow HW3_EN signal
-
-- qcom,pin-ctrl-hpm:
- Usage: optional
- Value type: <u32>
- Description: Bit mask specifying which hardware pins should be used to
- force the regulator into high power mode, if any;
- supported bits are:
- 0 = ignore all hardware enable signals
- BIT(0) = follow HW0_EN signal
- BIT(1) = follow HW1_EN signal
- BIT(2) = follow HW2_EN signal
- BIT(3) = follow HW3_EN signal
- BIT(4) = follow PMIC awake state
-
-- qcom,vs-soft-start-strength:
- Usage: optional
- Value type: <u32>
- Description: This property sets the soft start strength for voltage
- switch type regulators; supported values are:
- 0 = 0.05 uA
- 1 = 0.25 uA
- 2 = 0.55 uA
- 3 = 0.75 uA
-
-- qcom,saw-slave:
- Usage: optional
- Value type: <boo>
- Description: SAW controlled gang slave. Will not be configured.
-
-- qcom,saw-leader:
- Usage: optional
- Value type: <boo>
- Description: SAW controlled gang leader. Will be configured as
- SAW regulator.
-

-
- regulators {
- compatible = "qcom,pm8941-regulators";
- vdd_l1_l3-supply = <&s1>;
-
- s1: s1 {
- regulator-min-microvolt = <1300000>;
