[PATCH 4/4 v2] ARM: dts: Ux500: Add MCDE and Samsung display

[Linus Walleij]

This adds and updates the device tree nodes for the MCDE
display controller and connects the Samsung display to
the TVK1281618 user interface board (UIB) so we get
nicely working graphics on this reference design.

Signed-off-by: Linus Walleij <linus.walleij at linaro.org>

ChangeLog v1->v2:
- Drop the port graph links between DSI host and children
  and just let the panel be the child of its DSI port.
- Move the DSI HS and LP/ES clocks to be properties on
  the DSI host nodes.
