| * Palmas general purpose ADC IP block devicetree bindings |
| |
| Required properties: |
| - compatible : Must be "ti,palmas-gpadc". |
| |
| Optional sub-nodes: |
| ti,channel0-current-microamp: Channel 0 current in uA. |
| Valid values 0uA, 5uA, 15uA, 20uA. |
| ti,channel3-current-microamp: Channel 3 current in uA. |
| Valid value 0uA, 10uA, 400uA, 800uA. |
| ti,enable-channel3-dual-current: Enable dual current on channel 3. |
| ti,enable-extended-delay: Enable extended delay. |
| |
| Optional sub-node: |
| The Palmas ADC node has optional subnode to define the iio mapping. |
| It is the name with "iio_map". This node has again subnode to define |
| the property of the channel. The sub subnode has following properties: |
| - ti,adc-channel-number: ADC channel numbber. |
| - ti,adc-consumer-device: Consumer device name. |
| - ti,adc-consumer-channel: ADC consumer channel name. |
| |
| Example: |
| |
| pmic { |
| compatible = "ti,twl6035-pmic", "ti,palmas-pmic"; |
| ... |
| gpadc { |
| compatible = "ti,palmas-gpadc"; |
| interrupts = <18 0 |
| 16 0 |
| 17 0>; |
| ti,channel0-current-microamp = <5>; |
| ti,channel3-current-microamp = <10>; |
| iio_map { |
| ch1 { |
| ti,adc-channel-number = <1>; |
| ti,adc-consumer-device = "generic-adc-thermal.0"; |
| ti,adc-consumer-channel ="battery-temp-channel"; |
| }; |
| |
| ch6 { |
| ti,adc-channel-number = <6>; |
| ti,adc-consumer-device = "palmas-battery"; |
| ti,adc-consumer-channel ="vbat_channel"; |
| }; |
| }; |
| }; |
| ... |
| }; |
