The ARM Mali Midgard GPU family is present in a number of SoCs
from many different vendors such as Samsung Exynos and Rockchip.

Import the device tree bindings documentation from the r16p0
release of the Mali Midgard GPU kernel driver:

  https://developer.arm.com/-/media/Files/downloads/mali-drivers/kernel/mali-midgard-gpu/TX011-SW-99002-r16p0-00rel0.tgz

Remove the copyright and GPL licence header as deemed not necessary.

Redesign the "compatible" property strings to list all the Mali
Midgard GPU types and add vendor specific ones.

Drop the "clock-names" property as the Mali Midgard GPU uses only one
clock (the driver now needs to call clk_get with NULL).

Convert the "interrupt-names" property values to lower-case: "job",
"mmu" and "gpu".

Replace the deprecated "operating-points" optional property with
"operating-points-v2".

Omit the following optional properties in this initial version as they
are only used in very specific cases:

  * snoop_enable_smc
  * snoop_disable_smc
  * jm_config
  * power_model
  * system-coherency
  * ipa-model

Update the example accordingly to reflect all these changes, based on
rk3288 mali-t760.

dt-bindings: Updates for v4.12-rc1

This contains an update for the flow controller device tree binding as
well as the addition of the binding for the GP10B GPU found on the new
Tegra186 (Parker) SoC.

GP10B's definition is mostly similar to GK20A's and GM20B's. The only
noticeable difference is the use of power domains instead of a regulator
for power supply.

The operating-points-v2 binding gives a way to provide the OPP of the GPU.

The reserved memory bindings allow us to specify which memory areas our
buffers can be allocated from.

The ARM Mali Utgard GPU family is embedded into a number of SoCs from
Allwinner, Amlogic, Mediatek or Rockchip.

Add a binding for the GPU of that family.

This is a quite large renaming to consolidate display related bindings
into a single "display" directory from various scattered locations of
video, drm, gpu, fb, mipi, and panel. The prior location was somewhat
based on the Linux driver location, but bindings should be independent
of that.
