The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.

Add health property, which checks that temperature, voltage and current are
within limits for the battery. Limits can be programmed in non-volatile
memory.

temperatures
If enabled in the nPackCfg register, the Temp1, Temp2 and IntTemp registers
contain the temperature readings from the AIN1 thermistor, AIN2 thermistor
and internal die temperature respectively. Registers are shared between SBS
and normal IC functions and are always readable regardless of IC settings.

Charge full holds the calculated full capacity of the cell based on all
inputs from the ModelGauge m5 algorithm including empty compensation. A
new full-capacity value is calculated continuously as application
conditions change.

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

In this code, if devm_add_action_or_reset() fails, it will call
max1720x_unregister_ancillary() which in turn calls
i2c_unregister_device(). Thus the call to i2c_unregister_device() on the
following line is not required and is a double unregister. Delete it.

ModelGauge m5 and device configuration values are stored in nonvolatile
memory to prevent data loss if the IC loses power. Add read support for
the nonvolatile memory on MAX1720X devices.

The MAX17201 monitors a single cell pack. The MAX17205 monitors and
balances a 2S or 3S pack or monitors a multiple-series cell pack. Both
devices use a I2C interface.
