[PATCH 0/8] drm/imx: Introduce i.MX8qxp DPU DRM

[Liu Ying]

Hi,


This patch set introduces i.MX8qxp Display Processing Unit(DPU) DRM support.

DPU is comprised of a blit engine for 2D graphics, a display controller
and a command sequencer.  Outside of DPU, optional prefetch engines can
fetch data from memory prior to some DPU fetchunits of blit engine and
display controller.  The pre-fetchers support linear formats and Vivante
GPU tile formats.

Reference manual can be found at:
https://www.nxp.com/webapp/Download?colCode=IMX8DQXPRM


This patch set adds kernel modesetting support for the display controller part.
It supports two CRTCs per display controller, several planes, prefetch
engines and some properties of CRTC and plane.  Currently, the registers of
the controller is accessed without command sequencer involved, instead just by
using CPU.  DRM connectors would be created from the DPU KMS driver.


If people want to try this series, clock patches can be found at:
https://www.spinics.net/lists/arm-kernel/msg856137.html

and, power domain patches at:
https://www.spinics.net/lists/arm-kernel/msg856097.html


I will send other patch sets to add downstream bridges(embedded in i.MX8qxp)
to support LVDS displays.

A brief look at the pipe:
prefetch eng -> DPU -> pixel combiner -> pixel link -> pixel to DPI(pxl2dpi) ->
LVDS display bridge(LDB)


Patch 1 ~ 3 add dt-bindings for DPU and prefetch engines.
Patch 4 is a minor improvement of a macro to suppress warning as the KMS driver
uses it.
Patch 5 introduces the DPU DRM support.
Patch 6 updates MAINTAINERS.
Patch 7 & 8 add DPU and prefetch engines support in the device tree of
i.MX8qxp MEK platform.


Welcome comments, thanks.
