From f373e8c0639f1720d2d0fe414990f504e113c2ba Mon Sep 17 00:00:00 2001 From: Ryan Mallon Date: Tue, 10 Feb 2009 21:02:08 +0100 Subject: [ARM] 5373/2: Add gpiolib support to AT91 Add support for gpiolib, including debugfs output, to the AT91 family. The at91_get/set_gpio_value calls still exist since they are used by the atmel serial driver.

There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.
