This patchset is based on the git(branch name: exynos-drm-next) which is
maintained by Inki Dae.

This patchset adds 2 new device drivers, Exynos54333 decon and mic, and adds
support for Exynos5433 mipi dsi. To enable display in a Exynos5433 board,
decon(display controller), MIC(Mobile image compressor), mipi dsi, and panel
have to be turned on. This patchset contains support for 3 drivers for SoC
level devices.

Changes for v2:
- change config, file, and variable names of decon to represnt exynos5433
instead of exynos to distinguish them from exynos7 decon
- change the initialization order of decon to make it initialized in order like
FIMD or exynos7 decon
- make mic driver to be registered by exynos drm driver instead as a module
- change the description of mic driver in documentation
- add module author at the top of the source file removing MODULE_OWNER,
- change the author of "drm/exynos: dsi: add support for Exynos5433 SoC" to
Hyungwon Hwang by the previous author's will

Changes for v3:
< Decon >
- fail fast when the proper image format is not set
- remove unnecessary checking code
- add and modify the function to make DPMS work well
< MIC >
- move if statement out of function, so that the function is not called
- Make it use syscon framework for controlling system register
< DSI >
- separate the previous one patch to three
- renaming patch: rename pll clock to sclk clock
- generalizing patch: generalize the way to getting address and values
- Exynos5433 patch: adds support for Exynos5433 dsi
- use defines for more readable code
- fix typos

Changes for v4:
- rebased to exynos-drm-next with the clean-up patchset by Gustavo Padovan.

Changes for v5:
- separated the refactoring patch of MIPI DSI driver into 3 patches
- added the patch to make DSI driver compatiable with the old clock name
- added the patch to rename the DSI driver's clock
- rename the newly added dsi variables for clarity

Changes for v6:
- Clean up the build dependencies of Exynos DRM devices as preparation
- Introduce new common function drm_iommu_attach_device_if_possible()
- Add support for atomic modeset in Exynos5433 decon driver

Hyungwon Hwang (14):
  drm/exynos: remove the dependency of DP driver for ARCH_EXYNOS
  drm/exynos: Add the dependency for DRM_EXYNOS to DPI/DSI/DP
  drm/exynos: add drm_iommu_attach_device_if_possible()
  drm/exynos: fix the input prompt of Exynos7 DECON
  of: add helper for getting endpoint node of specific identifiers
  drm/exynos: mic: add MIC driver
  drm/exynos: dsi: rename pll_clk to sclk_clk
  drm/exynos: dsi: add macros for register access
  drm/exynos: dsi: make use of driver data for static values
  drm/exynos: dsi: make use of array for clock access
  drm/exynos: dsi: add support for Exynos5433
  drm/exynos: dsi: add support for MIC driver as a bridge
  drm/exynos: dsi: do not set TE GPIO direction by input
  ARM: dts: rename the clock of MIPI DSI 'pll_clk' to 'sclk_mipi'

Joonyoung Shim (1):
  drm/exynos: add Exynos5433 decon driver
