Sleep and Wake up by GPIO on LS1028

[#1]

This document introduces basic concept of Power Management, LS1028 RCW configuration to enable GPIO, Linux Kernel source and device tree modification to support GPIO wakeup, Kernel configuration to enable sleep feature and GPIO wakeup driver, export GPIO pin and enable interrupt, Order system to sleep and trigger GPIO interrupt to wake up the system.

Is there any chance you have an image already built that does wake on GPIO? We just need to be able to sleep/wake the processor as soon as possible to do some qualification testing. There are a lot of dependencies that have to be worked around and it's taking much longer than anticipated to get this going.
