OMAP4460/PandaES: hang during resume
Quoted 6 lines · Kevin Hilman
Hi Santosh, Tero,
I just added my 4460/PandaES to my board farm for automated PM testing and see that basic suspend/resume tests don't work in mainline. It fails on v3.6 and linux-next,arm-soc/for-next.

Adding '
no_console_suspend' to the cmdline shows me that wakeup event is happening so the hang is somewhere during resume. I haven't dug any deeper than that.This works fine on 4430/Panda. Do you know of anything else we're missing in mainline for a basic suspend/resume test on 4430?
OMAP4460 has one ROM code BUG which impacts MPUSS OSWR. I suspect you are missing that Errata WA.
You need a patch [1] which is in Tero's CORE RET series.
Regards
Santosh

Ah, yes. The one where I asked you to q(re)write the change log a hundred times. How could I forget. ;)
Thanks for the reminder.
