1binding for LTC2941 and LTC2943 battery gauges
2
3Both the LTC2941 and LTC2943 measure battery capacity.
4The LTC2943 is compatible with the LTC2941, it adds voltage and
5temperature monitoring, and uses a slightly different conversion
6formula for the charge counter.

8Required properties:
9- compatible: Should contain "ltc2941" or "ltc2943" which also indicates the
10    type of I2C chip attached.
11- reg: The 7-bit I2C address.
12- lltc,resistor-sense: The sense resistor value in milli-ohms. Can be a 32-bit
13    negative value when the battery has been connected to the wrong end of the
14    resistor.
15- lltc,prescaler-exponent: The prescaler exponent as explained in the datasheet.
16    This determines the range and accuracy of the gauge. The value is programmed
17    into the chip only if it differs from the current setting. The setting is
18    lost when the battery is disconnected.

20Example from the Topic Miami Florida board:
21
22	fuelgauge: ltc2943@64 {
23		compatible = "ltc2943";
24		reg = <0x64>;
25		lltc,resistor-sense = <15>;
26		lltc,prescaler-exponent = <5>; /* 2^(2*5) = 1024 */
27	};
