From c21cde6fe1ba08b357c96071c71af6543f2863ec Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 21 Jul 2015 11:36:57 +0200 Subject: gpio: document interaction with other subsystems Now I am very fed up with people reinventing kernel wheels in userspace "just because they can" (read, sysfs). Put in a angry blurb in sysfs doc and put in a new file with pointers to other subsystem drivers utilizing GPIOs.
