IRQ wake from Standby

Discussion created by Humphrey bucknell on Jan 24, 2012

I would like to wake the CPU from Standby from a variety of sources all attached to GPIO pins.

Unfortunately the GPIO drive does not support irq_wake in arch/arm/plat-mxs/gpio.c or arch/arm/mach-mx23/gpio.c

Has anyone implemented this or could you give me some pointers about how to prepare the system to wake the CPU from Standby?
