LTC2943 and LTC2944 -is software compatible, uses a slightly different conversion formula -for the charge counter and adds voltage, current and temperature monitoring. - -Required properties: -- compatible: Should contain "lltc,ltc2941", "lltc,ltc2942", "lltc,ltc2943" - or "lltc,ltc2944" which also indicates the type of I2C chip attached. -- reg: The 7-bit I2C address. -- lltc,resistor-sense: The sense resistor value in milli-ohms. Can be a 32-bit - negative value when the battery has been connected to the wrong end of the - resistor. -- lltc,prescaler-exponent: The prescaler exponent as explained in the datasheet. - This determines the range and accuracy of the gauge. The value is programmed - into the chip only if it differs from the current setting.
