Regulator of AMS AS3722 PMIC.
|
|
Name of the regulator subnode must be "regulators".
|
|
|
|
Optional properties:
|
|
--------------------
|
|
The input supply of regulators are the optional properties on the
|
|
regulator node. The AS3722 is having 7 DCDC step-down regulators as
|
|
sd[0-6], 10 LDOs as ldo[0-7], ldo[9-11]. The input supply of these
|
|
regulators are provided through following properties:
|
|
vsup-sd2-supply: Input supply for SD2.
|
|
vsup-sd3-supply: Input supply for SD3.
|
|
vsup-sd4-supply: Input supply for SD4.
|
|
vsup-sd5-supply: Input supply for SD5.
|
|
vin-ldo0-supply: Input supply for LDO0.
|
|
vin-ldo1-6-supply: Input supply for LDO1 and LDO6.
|
|
vin-ldo2-5-7-supply: Input supply for LDO2, LDO5 and LDO7.
|
|
vin-ldo3-4-supply: Input supply for LDO3 and LDO4.
|
|
vin-ldo9-10-supply: Input supply for LDO9 and LDO10.
|
|
vin-ldo11-supply: Input supply for LDO11.
|
|
|
|
Optional nodes:
|
|
--------------
|
|
- regulators : Must contain a sub-node per regulator from the list below.
|
|
Each sub-node should contain the constraints and initialization
|
|
information for that regulator. See regulator.txt for a
|
|
description of standard properties for these sub-nodes.
|
|
Additional custom properties are listed below.
|
|
sd[0-6], ldo[0-7], ldo[9-11].
|
|
|
|
Optional sub-node properties:
|
|
----------------------------
|
|
ams,ext-control: External control of the rail. The option of
|
|
this properties will tell which external input is
|
|
controlling this rail. Valid values are 0, 1, 2 ad 3.
|
|
0: There is no external control of this rail.
|
|
1: Rail is controlled by ENABLE1 input pin.
|
|
2: Rail is controlled by ENABLE2 input pin.
|
|
3: Rail is controlled by ENABLE3 input pin.
|
|
ams,enable-tracking: Enable tracking with SD1, only supported
|
|
by LDO3.
|
