Documentation for Regmap API?

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@xxxxxxxxxx>
L: linux-kernel@xxxxxxxxxxxxxxx
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
