Required properties:
|
- compatible : Must be "ti,palmas-gpadc".
|
- #io-channel-cells: Should be set to <1>.
|
|
Optional sub-nodes:
|
ti,channel0-current-microamp: Channel 0 current in uA.
|
Values are rounded to derive 0uA, 5uA, 15uA, 20uA.
|
ti,channel3-current-microamp: Channel 3 current in uA.
|
Values are rounded to derive 0uA, 10uA, 400uA, 800uA.
|
ti,enable-extended-delay: Enable extended delay.
|
|
Example:
|
|
pmic {
|
compatible = "ti,twl6035-pmic", "ti,palmas-pmic";
|
...
|
gpadc {

compatible = "ti,palmas-gpadc";
|
interrupts = <18 0
|
