Here are logs for low power transition, all platforms passed, properly
transitioned power domains with mem sleep using wakeup_timer to wake.

Low Power transition on v3.17-rc4 with patches applied, omap2plus_defconfig
(OMAP3 and OMAP4):

 1: BeagleBoard-XM: http://fpaste.org/133215/
 2: OMAP3430-Labrador(LDP): http://fpaste.org/133225/
 3: n900: http://fpaste.org/133244/
 4: pandaboard-es:  http://fpaste.org/133213/
 5: pandaboard-vanilla: http://fpaste.org/133214/
 6: sdp3430: http://fpaste.org/133246/

Boot on v3.17-rc4 with patches applied, omap2plus_defconfig:

 1: am335x-evm:  Boot PASS: http://fpaste.org/133179/
 2:  am335x-sk:  Boot PASS: http://fpaste.org/133180/
 3: am3517-evm:  Boot PASS: http://fpaste.org/133181/
 4:  am37x-evm:  Boot PASS: http://fpaste.org/133182/
 5: am43xx-epos:  Boot PASS: http://fpaste.org/133183/
 6: am43xx-gpevm:  Boot PASS: http://fpaste.org/133184/
 7: BeagleBoard-XM:  Boot PASS: http://fpaste.org/133191/
 8: beagleboard-vanilla:  Boot PASS: http://fpaste.org/133192/
 9: beaglebone-black:  Boot PASS: http://fpaste.org/133193/
10: beaglebone:  Boot PASS: http://fpaste.org/133194/
11: craneboard:  Boot PASS: http://fpaste.org/133186/
12: dra7xx-evm:  Boot PASS: http://fpaste.org/131396/
13: OMAP3430-Labrador(LDP):  Boot PASS: http://fpaste.org/133206/
14:       n900:  Boot PASS: http://fpaste.org/133207/
15:  omap5-evm:  Boot PASS: http://fpaste.org/133208/
16: pandaboard-es:  Boot PASS: http://fpaste.org/133187/
17: pandaboard-vanilla:  Boot PASS: http://fpaste.org/133188/
18:    sdp2430:  Boot PASS: http://fpaste.org/133189/
19:    sdp3430:  Boot PASS: http://fpaste.org/133212/
TOTAL = 19 boards, Booted Boards = 19, No Boot boards = 0

Again, all pass. I have also tested with next AM335x Suspend/Resume
implementation, next version will use generic sram driver to allocate for
low-level assembly code, and that works fine as well.

Dave
