Changes to max1721x_battery.c:
- reading manufacturer, model name and serial number is only possible
when SBS functions of the IC are enabled.(nNVCfg0.enSBS) Factory
default is off. Manufacturer is "Maxim Integrated" and the model name
can be derived by register MAX172XX_DEV_NAME. Serial number is not
available anymore.
- According to the datasheet MAX172XX_BAT_PRESENT is at BIT(3) not
BIT(4). Furthermore the naming is misleading, when BIT(3) is set the
battery is not present.
- Removed DeviceName, ManufacturerName and SerialNumber from struct
max17211_device_info
Changes in V2:
- Changed E-Mail in Patch (2/2) Signed-Off
Changes in V3:
- Changed E-Mail in Patch (2/2) Author
Changes in V4:
- add compatibles "maxim,max17201, "maxim,max17205" in bindings
- use generic node name fuel-gauge@36 instead of max17201@36 in bindings
- remove status in bindings
- fix spelling mistakes in commit message
- fix indentation in Kconfig
- fix typos in max1720x_battery.c
- Drop bat and bat_desc from info struct.
- MAX172XX_DEV_NAME and MAX172XX_DESIGN_CAP aren't volatile, adjust regmap
- constify max1720x_manufacturer, max17201_model, max17205_model
- constify max1720x_battery_props
- Remove braces around reg in max172xx_current_to_voltage
- Skip initialization of reg_val in max1720x_battery_get_property
- Remove braces around FIELD_GET() in max1720x_battery_get_property
- In case POWER_SUPPLY_PROP_PRESENT there is an early return if ret < 0.
Return 0 if regmap_read fails, device is not responding in case
battery is not inserted
- Implement multi-byte readings instead of i2c_smbus_read_word_data
- Drop ancillary from info
- Drop both calls to i2c_set_clientdata in max1720x_probe
- Get rid of max1720x_remove
- Remove comma after sentinel in max1720x_of_match
- Fix alignment of max1720x_i2c_driver
- Fix return value of dev_err_probe after max1720x_probe_sense_resistor
to use ret instead of PTR_ERR(info->bat)
Changes in V5:
- oneOf with list and fallback in bindings
- unevaluatedProperties: false in bindings
- switch back to i2c_smbus_read_word_data when reading from ancillary
- add psy_cfg.fwnode = dev_fwnode(dev) in max1720x_probe
- set max_register in max1720x_regmap_cfg to MAX172XX_ATAVCAP
- fix typo in define: MAX1720X_NRSENSE instead of MAX1720_NRSENSE
