Sandbox pmic
 
This device uses two drivers:
- drivers/power/pmic/sandbox.c (for parent device)
- drivers/power/regulator/sandbox.c (for child regulators)
 
This file describes the binding info for the PMIC driver.
 
To bind the regulators, please read the regulator binding info:
- doc/device-tree-bindings/regulator/sandbox.txt
 
Required PMIC node properties:
- compatible: "sandbox,pmic"
- reg = 0x40
 
Required PMIC's "emul" subnode,  with property:
- compatible: "sandbox,i2c-pmic"
 
With the above properties, the pmic device can be used for read/write only.
To bind each regulator, the optional regulator subnodes should exists.
 
Optional subnodes:
- ldo/buck subnodes of each device's regulator (see regulator binding info)
 
Example:
 
sandbox_pmic {
   compatible = "sandbox,pmic";
   reg = <0x40>;
 
   /* Mandatory for I/O */
   emul {
       compatible = "sandbox,i2c-pmic";
   };
};
