This patch series adds support for "standby" and "mem" power modes on the AT32AP700x CPUs.
I've also included a couple of fixes that should go in through other trees in order to ease testing: #1 fixes an oops on suspend and shutdown. Picked from the linux-mtd list. #2 is a quick-n-dirty hack for a build problem when CONFIG_PM=y #7 is a quick-n-dirty suspend/resume implementation for macb which prevents it from waking up the system all the time.
This patch series is meant to apply to the avr32-arch branch of the avr32 tree. It won't apply to 2.6.24, and even if you fix the conflicts it won't work because of Kconfig changes. I've made the necessary fixes and pushed it out to
git://git.kernel.org/pub/scm/linux/kernel/git/hskinnemoen/avr32-2.6.git atmel-2.6.24
and the result seems to work fine.
I haven't measured the time it takes to resume the system, but it feels instantaneous, at least on the ATNGW100. The delay is more noticeable on ATSTK1000 since it needs to power up the LCD panel (the ltv350qv panel takes about 100 ms to power up).
