Merge branch 'devfreq-for-next' of git://git.infradead.org/users/kmpark/linux-samsung into pm-devfreq
* 'devfreq-for-next' of git://git.infradead.org/users/kmpark/linux-samsung: (765 commits) PM/Devfreq: Add Exynos4-bus device DVFS driver for Exynos4210/4212/4412. pci: Fix hotplug of Express Module with pci bridges i2c-eg20t: correct the driver init order of pch_i2c_probe() I2C: OMAP: fix FIFO usage for OMAP4 i2c-s3c2410: Fix return code of s3c24xx_i2c_parse_dt_gpio i2c: i2c-s3c2410: Add a cpu_relax() to busy wait for bus idle Linux 3.2-rc6 Revert "drm/i915: fix infinite recursion on unbind due to ilk vt-d w/a" btrfs: lower the dirty balance poll interval drm/i915/dp: Dither down to 6bpc if it makes the mode fit drm/i915: enable semaphores on per-device defaults drm/i915: don't set unpin_work if vblank_get fails drm/i915: By default, enable RC6 on IVB and SNB when reasonable iommu: Export intel_iommu_enabled to signal when iommu is in use drm/i915/sdvo: Include LVDS panels for the IS_DIGITAL check drm/i915: prevent division by zero when asking for chipset power drm/i915: add PCH info to i915_capabilities drm/i915: set the right SDVO transcoder for CPT drm/i915: no-lvds quirk for ASUS AT5NM10T-I sched: Fix select_idle_sibling() regression in selecting an idle SMT sibling ...
