From 1fbece150a230d0ab447cfb2fc4df10fb89f0d8c Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sat, 1 Jul 2006 13:39:55 -0700 Subject: [PATCH] [PATCH] pcmcia: at91_cf update More correct AT91 CF wakeup logic ... only enable/disable the IRQ wakeup capability, not the IRQ itself. That way the we know that the IRQ will be disabled correctly, in suspend/resume logic instead of ARM IRQ code. Most of the pin multiplexing setup has moved to the devices.c setup code.
