About doc/usage directory

[Jaehoon Chung]

Hi all,

I have a question about usage page.
I have found files under doc/usage/.  It's description how to use each command.
But there is not mmc.rst and file relevant to power command.(regulator, pmic, etc)
If someone didn't have any plan, I want to update file relevant to mmc and pmic command.

Is there any rule to update it? My goal is to apply next release.

If someone are already doing this, let me know, plz.

Best Regards,
Jaehoon Chung
