   1 * 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.
