| 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 |
| 16 0 |
| 17 0>; |
| #io-channel-cells = <1>; |
| ti,channel0-current-microamp = <5>; |
| ti,channel3-current-microamp = <10>; |
| }; |
| }; |
| ... |
| }; |
