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";

};
