From 32993b793fb07784fd1380004f5b34f31f9105d5 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 10 May 2007 22:22:17 -0700 Subject: [PATCH] Documentation/gpio.txt mentions GENERIC_GPIO Documentation/gpio.txt should mention the Kconfig GENERIC_GPIO flag, for platforms to declare when relevant. This should help minimize goofs like omitting it, or not depending on it when needed.
