1* Dialog Semiconductor SLG51000 Voltage Regulator
2
3Required 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
18Optional 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
23Sub-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
37Optional properties for regulators:
38- enable-gpios : Specify a valid GPIO for platform control of the regulator.
