power: supply: Add driver for TI BQ25630 charger
TI BQ25630 is a battery charger that is I2C controlled. Despite its
model name, it is rather different from the other devices in the BQ256xx
family; it has a completely different register layout and some other
additional functionality (see the datasheet for more details [1]).
The most "annoying" thing is that it has two different register lengths:
8-bit and 16-bit. Moreover, the 16-bit registers are further partitioned
into either being little- or big-endian... Luckily, `regmap` has support
for multiple `regmap_config`s (by setting unique names). Therefore, use
three different `regmap_config`s for the corresponding registers. ADC
functionality has been left out, due to it not having any real-world
use-cases.
The `enum power_supply_property` values are straightforward to map. Some
properties are clamped (e.g. voltage/current ranges). Common
`bq25630_read/write_limit()` functions for this are therefore suitable.
Interrupts are sent whenever a state change is detected. Save the state
status registers in `bq25630_data` and `memcmp()` this in order to
decide if `power_supply_changed()` should be called or not. The actual
state values are in (and fetched from) the other
`power_supply_property`-mapped registers.
