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 .../bindings/power/supply/maxim,max17040.yaml | 31 +++++++++++++++++++ arch/arm/configs/s5pv210_defconfig | 1 + drivers/power/supply/Kconfig | 2 +- drivers/power/supply/max17040_battery.c | 27 ++++++++++++++++ 4 files changed, 60 insertions(+), 1 deletion(-) -- 2.39.2
