* Dialog Semiconductor SLG51000 Voltage Regulator
2
+
3
+
Required properties:
4
+
- compatible : Should be "dlg,slg51000" for SLG51000
5
+
- reg : Specifies the I2C slave address.
6
+
- xxx-supply: Input voltage supply regulator for ldo3 to ldo7.
7
+
These entries are required if regulators are enabled for a device.
8
+
An absence of these properties can cause the regulator registration to fail.
9
+
If some of input supply is powered through battery or always-on supply then
10
+
also it is required to have these parameters with proper node handle of always
11
+
on power supply.
12
+
vin3-supply: Input supply for ldo3
13
+
vin4-supply: Input supply for ldo4
14
+
vin5-supply: Input supply for ldo5
15
+
vin6-supply: Input supply for ldo6
16
+
vin7-supply: Input supply for ldo7
17
+
18
+
Optional properties:
19
+
- interrupt-parent : Specifies the reference to the interrupt controller.
20
+
- interrupts : IRQ line information.
21
+
- dlg,cs-gpios : Specify a valid GPIO for chip select
22
+
23
+
Sub-nodes:
24
+
- regulators : This node defines the settings for the regulators.
25
+
The content of the sub-node is defined by the standard binding
26
+
for regulators; see regulator.txt.
27
+
28
+
The SLG51000 regulators are bound using their names listed below:
29
+
ldo1
30
+
ldo2
31
+
ldo3
32
+
ldo4
33
+
ldo5
34
+
ldo6
35
+
ldo7
36
+
37
+
Optional properties for regulators:
38
+
- enable-gpios : Specify a valid GPIO for platform control of the regulator.
39
+
