[RFC][PATCH 0/2] Initial support for ARM Mali Display Processors

[Liviu Dudau]

Hello,

Here is the public first version of the driver for the Mali Display Processors.
Currently, the driver supports the Display Engine found in Mali DP500, DP550
and DP650, with up to 3 planes that can be rotated by the hardware. There are
features that the hardware supports that are not currently implemented in the
driver, but in the current form it is capable of supporting X11 using fbdev
emulation as well as Wayland with pixman rendering.

The patchset is submitted as an RFC to gather feedback and to catch early
mistakes in the driver. I would appreciate any comments that you might have as
well as code reviews if possible.

Many thanks,
Liviu
