[PATCH 00/10] Add Freescale i.MX8qxp Display Controller support

Hi,

This patch series aims to add Freescale i.MX8qxp Display Controller support.

The controller is comprised of three main components that include a blit
engine for 2D graphics accelerations, display controller for display output
processing, as well as a command sequencer.

Previous patch series attempts to do that can be found at:
https://patchwork.freedesktop.org/series/84524/

This series addresses Maxime's comments on the previous one:
a. Split the display controller into multiple internal devices.
1) List display engine, pixel engine, interrupt controller and more as the
controller's child devices.
2) List display engine and pixel engine's processing units as their child
devices.

b. Add minimal feature support.
Only support two display pipelines with primary planes with XR24 fb,
backed by two fetchunits. No fetchunit dynamic allocation logic(to be done
when necessary).

c. Use drm_dev_{enter, exit}().

Since this series changes a lot comparing to the previous one, I choose to
send it with a new patch series, not a new version.

To follow up i.MX8qxp TRM, I changed the controller name to "Display Controller"
instead of the previous "DPU". "DPU" is only mentioned in the SoC block
diagram and represents the whole display subsystem which includes the display
controller and prefech engines, etc.
