Re: [Patch v2 00/14] Add power management support for MXS PHY

[Peter Chen <peter.chen@freescale.com>]

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
http://marc.info/?l=linux-arm-kernel&m=138243289017143&w=2
- 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.
