This patch series introduces a lot of changes to the existing DSIM bridge driver, by introdcing new registers and making register offsets configurable for different SoCs. These preliminary changes are followed by the introduction of support for Exynos7870's DSIM IP block. Work is heavily inspired and only possible due to Samsung's vendor kernel sources. Testing has been done with Samsung Galaxy J7 Prime (samsung-on7xelte), Samsung Galaxy A2 Core (samsung-a2corelte), and Samsung Galaxy J6 (samsung-j6lte), all with DSI video mode panels.
