Request to extend the fuel gauge driver to include support for LC709203F

[zpm1066]

Is your feature request related to a problem? Please describe.
Currently there's no driver for fuel gauge LC709203F. Some of the Adafruit ESP32 boards have LC709203F chip. Standalone LC709203F breakouts are also available to be used with a wide range of boards.

Describe the solution you'd like
I'd like to see the fuel gauge driver extended to include LC709203F. Currently, the driver supports MAX17048.

Describe alternatives you've considered
Purchasing new boards with MAX17048 fuel gauge is a possibility.

Additional context
Added LC709203F data sheet.

I can only encourage you to write a driver and submit a PR for this.

We cannot really take in requests or wishes for writing new drivers.

@henrikbrixandersen not an issue.
Any example on how to write a Zephyr driver? I’d be keen to do so. Thanks.

[henrikbrixandersen]

Yes! We have 1000+ examples of Zephyr drivers right here: https://github.com/zephyrproject-rtos/zephyr/tree/main/drivers :-)
Examples of other Fuel Gauge drivers can be found here: https://github.com/zephyrproject-rtos/zephyr/tree/main/drivers/fuel_gauge

I'd suggest starting with reading https://docs.zephyrproject.org/latest/introduction/index.html and https://docs.zephyrproject.org/latest/kernel/drivers/index.html

@henrikbrixandersen Thanks.
I’ll review the existing two fuel gauge drivers and get familiar with the device driver model.
