   1 Sandbox pmic
   2
   3 This device uses two drivers:
   4 - drivers/power/pmic/sandbox.c (for parent device)
   5 - drivers/power/regulator/sandbox.c (for child regulators)
   6
   7 This file describes the binding info for the PMIC driver.
   8
   9 To bind the regulators, please read the regulator binding info:
  10 - doc/device-tree-bindings/regulator/sandbox.txt
  11
  12 Required PMIC node properties:
  13 - compatible: "sandbox,pmic"
  14 - reg = 0x40
  15
  16 Required PMIC's "emul" subnode,  with property:
  17 - compatible: "sandbox,i2c-pmic"
  18
  19 With the above properties, the pmic device can be used for read/write only.
  20 To bind each regulator, the optional regulator subnodes should exists.
  21
  22 Optional subnodes:
  23 - ldo/buck subnodes of each device's regulator (see regulator binding info)
  24
  25 Example:
  26
  27 sandbox_pmic {
  28         compatible = "sandbox,pmic";
  29         reg = <0x40>;
  30
  31         /* Mandatory for I/O */
  32         emul {
  33                 compatible = "sandbox,i2c-pmic";
  34         };
  35 };
