Binding for Nokia N900 battery
|
||||
|
||||
The Nokia N900 battery status can be read via the TWL4030's A/D converter.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should contain one of the following:
|
||||
* "nokia,n900-battery"
|
||||
- io-channels: Should contain IIO channel specifiers
|
||||
for each element in io-channel-names.
|
||||
- io-channel-names: Should contain the following values:
|
||||
* "temp" - The ADC channel for temperature reading
|
||||
* "bsi" - The ADC channel for battery size identification
|
||||
* "vbat" - The ADC channel to measure the battery voltage
|
||||
|
||||
Example from Nokia N900:
|
||||
|
||||
battery: n900-battery {
|
||||
compatible = "nokia,n900-battery";
|
||||
io-channels = <&twl4030_madc 0>,
|
||||
<&twl4030_madc 4>,
|
||||
<&twl4030_madc 12>;
|
||||
io-channel-names = "temp",
|
||||
"bsi",
|
||||
"vbat";
|
||||
};
