--- Upgrade the power and reset button handling for the DSMG600:
arch/arm/mach-ixp4xx/dsmg600-power.c | 13 +++++++++---- * Remove the superfluous declaration of ctrl_alt_del().
1 file changed, 9 insertions(+), 4 deletions(-) * Convert GPIO and IRQ handling to use the <asm/gpio.h> api.
* Perform the reset on the release of the power button, so that
NAS devices which have been set to auto-power-on (by bridging
the power button) do not continuously power cycle.
* Remove all superflous constants from dsmg600.h

2 files changed, 75 insertions(+), 11 deletions(-) for at least two seconds. Do the reset on the release of the power
button, so that NAS devices which have been set to auto-power-on (by
bridging the power button) do not continuously power cycle.
* Remove all superflous constants from nas100d.h
* Add LED constants to nas100d.h while we're there.
Also, update the board LED setup code to use constants.
