The STC3117 provides a simple fuel gauge via I2C.
Add a DT schema to describe how to set it up in the device tree.

+description: |
+  The STC3117 includes the STMicroelectronics OptimGauge algorithm.
+  It provides accurate battery state-of-charge (SOC) monitoring, tracks
+  battery parameter changes with operation conditions, temperature,
+  and aging, and allows the application to get a battery state-of-health
+  (SOH) indication.
+
+  An alarm output signals low SOC or low voltage conditions and also
+  indicates fault conditions like a missing or swapped battery.
+
+  Datasheet is available at
+  https://www.st.com/resource/en/datasheet/stc3117.pdf

I asked you some questions on v2, then on v3 and no responses.

You implemented some changes but still did not answer my question. I am
not going to ask again, obviously expecting different result on the same
makes little sense.

No ack from me.

Best regards,
Krzysztof

You responded privately - I am not going to do any talks under NDA. I
also do not provide some sort of personal support service. Keep *ALL*
discussions public.

Explaining what you asked:

Some of these are from monitored-battery. Sense resistor should be
separate property. But different question is about missing resources,
like supplies (VCC) and interrupts. Just look at datasheet.

Best regards,
Krzysztof
