[PATCH 0/4] Refreshed PM workaround patches

[Högander Jouni]

Hi,

One more refreshed PM workaround set. Here are instructions, how to test
them:

To get Omap into retention, this patch set still depends on:
1. ARCH: OMAP: MUSB: Do not block sleep (Felipe Balbi)

Test:
1. Apply dependency patch and workaround set on top of them

2. Enable disabling/enabling of gpio2-6 and uart clocks on idle:
   $ echo 1 > /sys/power/clocks_off_while_idle

3. Try out static suspend:
   $ echo mem > /sys/power/state
   Wake up from suspend by entering character to serial console. This
   should print out:
   "Successfully put all powerdomains to target state"

4. Try out dynamic sleep:
   $ echo 1 > /sys/power/sleep_while_idle
   On Omap3430 SDP board VCORE_EN led can be used as an indicator. If
   it starts to blink after a while then Omap enters retention on
   idle. To make this work also display needs to be blanked.

Please ignore this set. It break 24xx build and patches contains
error. Sorry for this. I will send them again soon.
