Merge branch 'exynos-drm-next' of... 

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

Summaries:
- Add MIPI-DSI Driver, and dt bindigs
- Add S6E8AA0 MIPI-DSI based panel drivers, and dt bindings
- Add LD9040 parallel panel driver
 . this driver is placed in drivers/gpu/drm/panel, and it seems
   to be used for exynos drm as of now,
- Some fixups

Changelog v2:
- Remove super device support, and relevant dt bindings for more reviews.
- Fix module build errors you pointed out.
- Re-based it to drm-next again.

Samsung LD9040 AMOLED LCD parallel RGB panel with SPI control bus



Required properties:

  - compatible: "samsung,ld9040"

  - reg: address of the panel on SPI bus

  - vdd3-supply: core voltage supply

  - vci-supply: voltage supply for analog circuits

  - reset-gpios: a GPIO spec for the reset pin

  - display-timings: timings for the connected panel according to [1]



The panel must obey rules for SPI slave device specified in document [2].



Optional properties:

  - power-on-delay: delay after turning regulators on [ms]

  - reset-delay: delay after reset sequence [ms]

  - panel-width-mm: physical panel width [mm]

  - panel-height-mm: physical panel height [mm]



The device node can contain one 'port' child node with one child

'endpoint' node, according to the bindings defined in [3]. This

node should describe panel's video bus.
