Hi Marek,

I have tried this patchset as well as my chipidea runtime pm patchset
at imx28 evk, it works ok except below two problems:

- Without CONFIG_MFD_SYSCON causes build error, fixed by below patches
- Unbalanced IRQ wake disable kernel warning when system resume if
enabled wakeup setting , it may mx28 platform problem, I will discuss
with shawn about it.
