+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.

See https://patchwork.ozlabs.org/patch/1402850

The base for the patch is generally the last rc1. Any dependencies
should be noted.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

I'll fix the yamllint warnings in v2. Sorry.

The dtschema/dtc errors in patch 1/8, 2/8 and 3/8 are caused by LPCG
clock patch dependence(the patch 2/5 in the below series) which I
should have noted:
