The patch titled
add CONFIG_GENERIC_GPIO
has been removed from the -mm tree. Its filename was
add-config_generic_gpio.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: add CONFIG_GENERIC_GPIO
From: David Brownell <david-b@xxxxxxxxxxx>
Most drivers using GPIOs already know they are running on a system that
supports the generic GPIO calls, because of other platform dependencies.
But the generic GPIO-based LED and input button drivers can't know that.
So this patch adds a Kconfig hook, GENERIC_GPIO, to mark the platforms
where <asm/gpio.h> will do the right thing. Currently that's a bunch of
ARMs, and AVR32; more are on the way.
It also fixes a dependency bug for the gpio button input driver; it was
wrong to start with, now it covers all platforms with GENERIC_GPIO.
