[PATCH v2 00/13] Support for Exynos7870 DSIM bridge

[Kaustabh Chakraborty]

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.
