I'm trying to use on imx53qsb with mc34708 pmic. And stuck with resume from suspend. It stops to resume after 5-15 cycles.(maybe more)
WEC7 BSP works fine on the same board.
It doesn't matter what IRQ line I'am using to wake up, I tried buttons with
gpio-key,wakeup; in dts, and waking up from ttymxc0 ( debug console)
echo enabled > power/wakeup
after some I see
[ 1394.555344] PM: Syncing filesystems ... done.
[ 1394.746289] PM: Preparing system for mem sleep

And thats it.
Looks like About iMX53 suspend/resume issue is totally related to my issue. But still nobody solved it?
