[RFC PATCH] gpio: add GPIO hogging mechanism

[Boris BREZILLON]

Hello,

This a proposal for the GPIO hog concept described by Linus (Walleij).

I know there were work in progress on this subject (Jiri and Ben at least:
https://www.mail-archive.com/linux-gpio@xxxxxxxxxxxxxxx/msg00864.html),
so don't hesitate to point out if something similar has already been posted.

Best Regards,

Boris
