Where is any DTS user of this? You have entire cover letter to explain
the background WHY you are doing this.

This new lithium-ion-silicon-anode chemistry is intended for the
Kaanapali platform, where we validate the silicon-anode Li-ion cells.
The bindings and driver changes were tested with the Kaanapali device.

I will update the background in the cover-letter in the next revision.

Again: DTS. Please answer that part.

Actually, the device-chemistry property (lithium-ion-silicon-anode) is
not added in Kaanapali DT because this battery chemistry and other
information is obtained from the charger firmware, which runs on
the remote processor.

I added this change mainly for completeness. If you feel it isn’t
necessary, I’m fine with dropping it and proceeding without this change.

Rakesh
