v10->v11:
* No change.

v9->v10:
* No change.

v8->v9:
* No change.

v7->v8:
* No change.

v6->v7:
* Add Rob's R-b tag back.

v5->v6:
* Use graph schema. So, drop Rob's R-b tag as review is needed.

v4->v5:
* No change.

v3->v4:
* Improve compatible property by using enum instead of oneOf+const. (Rob)
* Add Rob's R-b tag.

v2->v3:
* No change.

v1->v2:
* Fix yamllint warnings.
* Require bypass0 and bypass1 clocks for both i.MX8qxp and i.MX8qm, as the
display controller subsystem spec does say that they exist.
* Use new dt binding way to add clocks in the example.
* Trivial tweaks for the example.

+description: |
+ The Freescale i.MX8qm/qxp Display Processing Unit(DPU) is comprised of two
+ main components that include a blit engine for 2D graphics accelerations
+ and a display controller for display output processing, as well as a command
+ sequencer.
