There is a force load option when loading the driver as a module.
This adds the equivalent methodology for the binding path.
Though I suppose you could in fact just force load if the gpio detect
isn't present.
Thats a good idea, just wasn't the existing driver flow. I can't think
of any reason why we couldn't do that though.
I'll update the patch and resubmit V3
Will add a note about it in the docs
Please note I'd submitted this incorrectly when using our patch script
last time, it's now correctly part of the combined patch

Notes:
Add device tree binding documentation for addition of force_load
boolean value to allow loading a battery during boot even if not
present at that time.

What's a module? That's Linux specific and nothing to do with the
binding.
Can't you just force load if sbs,battery-detect-gpios is not present?
