binding for LTC2941 and LTC2943 battery gauges
Both the LTC2941 and LTC2943 measure battery capacity.
The LTC2943 is compatible with the LTC2941, it adds voltage and
temperature monitoring, and uses a slightly different conversion
formula for the charge counter.
Required properties:
- compatible: Should contain "ltc2941" or "ltc2943" 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. The setting is
lost when the battery is disconnected.
Example from the Topic Miami Florida board:
fuelgauge: ltc2943@64 {
compatible = "ltc2943";
reg = <0x64>;
lltc,resistor-sense = <15>;
lltc,prescaler-exponent = <5>; /* 2^(2*5) = 1024 */
};
Binding for the LTC2952 PowerPath controller
This chip is used to externally trigger a system shut down. Once the trigger has
been sent, the chips' watchdog has to be reset to gracefully shut down.
If the Linux systems decides to shut down it powers off the platform via the
kill signal.

A full powerdown can be triggered via the kill signal.
Required properties:
- compatible: Must contain: "lltc,ltc2952"
- trigger-gpios: phandle + gpio-specifier for the GPIO connected to the
chip's trigger line
- watchdog-gpios: phandle + gpio-specifier for the GPIO connected to the
chip's watchdog line
- kill-gpios: phandle + gpio-specifier for the GPIO connected to the
chip's kill line
Optional properties:
- trigger-gpios: phandle + gpio-specifier for the GPIO connected to the
chip's trigger line. If this property is not set, the
trigger function is ignored and the chip is kept alive
until an explicit kill signal is received
