Subject: [PATCH v3 0/4] Add optional properties to MAX17040
Date:   Mon, 31 Jul 2023 10:36:09 +0300

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. With that said, the driver got dependency on CONFIG_IIO which
was added to Kconfig. All defconfigs apart s5pv210_defconfig have IIO
already enabled so only s5pv210_defconfig needed adjustment.

---
Changes from v2:
- documentation: fixed typo i2c0 > i2c
- added dependency on CONFIG_IIO
- enabled CONFIG_IIO for s5pv210_defconfig to avoid regressions (all other
  defconfigs which include max17040 already have IIO enabled)

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 (4):
  dt-bindings: power: supply: maxim,max17040: update properties
  power: max17040: pass status property from supplier
  power: max17040: get thermal data from adc if available
  ARM: configs: s5pv210_defconfig: enable IIO required by MAX17040
