[PATCH 0/5] Support for Exynos7870's display stack (DECON, MIPIPHY, DSIM, etc.)

[Kaustabh Chakraborty]

Exynos7870 has a IP subsystem in its architecture dedicated to display
management. Notably, this block includes the Display Enhancement
Controller (DECON), and the DSI Master (DSIM).

The following series and its sub-series implement all components for a
functioning display pipeline. All vital information which helped shaping
up the patches have been retrieved from Exynos7870 vendor kernel sources
as provided by Samsung.

Testing has been done on all three devices available upstream, i.e.
Samsung Galaxy J7 Prime (samsung-on7xelte), Samsung Galaxy A2 Core
(samsung-a2corelte), and Samsung Galaxy J6 (samsung-j6lte). Regrettably,
I've only been able to test the functionality on video mode, as none of
the devices have panels working in command mode.

This series implements changes in the SoC subsystem, which includes
devicetree additions. It depends on all sub-series listed below:
