[U-Boot] [PATCH v2 00/25] exynos: video: Convert exynos LCD driver to use driver model

[Simon Glass]

This series converts the exynos LCD driver to work with driver model. Only
the eDP display is converted - the MIPI display is left mostly alone as I
do not have a device to test with.

The conversion involves some refactoring to simplify the code, reduce the
amount of global/static data and allow boards to be built without LCD
support.

The series is tested with snow, spring, pit and pi. It disables LCD on other
exynos boards so that they will still build with these changes. Further work
will be needed (by someone with a board) to convert the others. I am not
sure when this series can be applied.

The series also brings in device tree features from Linux v4.4. It would be
useful to do a full sync with the kernel on these files, but this is really
a job for the Samsung maintainer :-)

The series is available at u-boot-dm/rkg-working.

Changes in v2:
- Rebase to master
