Hi,

I've been exploring the Regmap API and
was wondering if there’s a dedicated documentation page
that provides an overview or explanation of the API itself.

So far, I’ve looked into the following:

1. https://docs.kernel.org/driver-api/index.html
2. The Documentation/ directory in both the mainline and linux-next trees.
3. The regmap tree mentioned in the MAINTAINERS file:
---
   REGISTER MAP ABSTRACTION
   M:  Mark Brown <broonie at kernel.org>
   L:  linux-kernel at vger.kernel.org
   S:  Supported
   T:  git git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap.git
   F:  Documentation/devicetree/bindings/regmap/
   F:  drivers/base/regmap/
   F:  include/linux/regmap.h
---

Despite checking these locations,
I couldn’t find a dedicated document explaining the Regmap API in detail.

1. Is there any such documentation available that I might have missed?

2. If not, I’d be happy to contribute and help write one.
Should I bring this up on the linux-doc mailing list for further guidance on how to proceed?

Any pointers or suggestions would be greatly appreciated.

Thanks a lot,
Ali
