[PATCH v2 0/2] PM / devfreq: Add delayed timer for polling

[Chanwoo Choi]

Add the delayed timer to devfreq framework in order to support
the periodical polling mode without stop caused by CPU idle state.
Some Non-CPU device must need to monitor the device status like
utilization regardless of CPU state.

- patch1 explains the detailed reason why the delayed timer is required.
- patch2 initializes that exynos5422-dmc device use delayed timer as default
instead of deferrable timer.

Changes from v2:
- Add reviewed-by tag
- Fix typo on patch description
- Remove 'RFC' work from patch title
- Check whether 'df->governor' is NULL or not on timer_store()
