Subject: [PATCH v2 0/2] Exynos5422 DMC: adjust to new devfreq monitoring mechanism

Hi all,

This is a v2 patch set adjusting Exynos5422 DMC to the new devfreq monitoring
mechanism. This time the IRQ mode is explicitly controlled using module
parameter (in default the driver uses polling mode = devfreq monitoring).

The detailed cover letter describing the topic can be found here [1].

The patches should apply on top of Chanwoo's devfreq-next branch, where
the new devfreq mechanism is queued [2]. If there is no objections
I think they can go via this tree, since they logically use it.

Changes:
v2:
- added Reviewed-by from Chanwoo for patch 1/2
- added module_param which controls the mode in which the driver operates
- switched in default to devfreq monitoring mechanism instead of interrupts

Regards,
Lukasz Luba
