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";
|
||
|
|
};
|
||
|
|
};
