Subject: [PATCH v2 0/3] Add optional properties to MAX17040

Extend properties supported by max17040 fuel gauge if it is accompanied
by different devices.

If max17040 is coupled with a charger, pass charger status since it should
match and max17040 has no dedicated status detection ability.

max17040_get_online can be reused for PRESENT property since if it is
online it must be present.

Finally, max17040 may be coupled with a dedicated thermal sensor which
monitors battery temperature so lets add support for iio channel to match
hw setup.

---
Changes from v1:
- documentation dropped monitored-battery and power-supplies (inherited
  from inclusion)
- dropped passing charger health as battery health
- dropped patch for simple battery cell support
- switched iio_read_channel_raw to iio_read_channel_processed_scale
- switched iio_channel_get to devm_iio_channel_get
- re-organized implementation of temp channel (implemented in way 
  *_get_optional functions usually act)

Svyatoslav Ryhel (3):
  dt-bindings: power: supply: maxim,max17040: update properties
  power: max17040: pass status property from supplier
  power: max17040: get thermal data from adc if available
