Subject: [PATCH 08/14] ARM: OMAP2: Add functions to save and restore pinctrl context.

Hi,

So where's the patch adding callers to this code?

If this cannot be done from regular driver suspend/resume calls,
this probably should be done from cpu_pm notifiers CPU_PM_ENTER and
CPU_PM_EXIT. We should also do the same for GPIO BTW.

BTW, the subject line is wrong here, it should be "pinctrl" :)

Regards,

Tony
