Merge branch 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next 

Summary:
- change exynos file license
  . Most of exynos files had been copied from some randome
    file and not updated correctly(wrong company name used).
    This was our mistakes so chagnes it correctly. For this,
    I'm not sure that this patch should go to -fix or -next.
    So please give me any comment if there is any problem.
- consider buffer allocation without iommu
  . Without iommu, dma_alloc_attrs function allocates some
    memory region and returns cpu address so this patch makes
    the cpu address to be set to buf->kvaddr correctly
- cleanups to ipp relevant codes.
- use common finish page flip function
  . to avoid the duplication of same code, use
    exynos_drm_crtc_finish_pageflip function commonly instead
    of each one.
- fix fimd resume issue.
  . when fimd was turned off by suspend, there was one issue that
    the fimd wasn't turned on by resume so fix it chaing resume
    condition.

* 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: (25 commits)
