#1614655 — [PATCH v2 0/5] Add ARM Mali Midgard device tree bindings and gpu node for rk3288

The ARM Mali Midgard GPU kernel driver is only available
out-of-tree and is not going to be merged in its current form.
However, it would be useful to have its device tree bindings
merged.  In particular, this would enable distributions to create
working driver packages (dkms...) without having to patch the
kernel.

The bindings for the earlier Mali Utgard GPU family have already
been merged, so this is essentially the same scenario but for
newer GPUs (Mali-T604 ~ Mali-T880).

This series of patches first imports the bindings from the latest
driver release with some clean-up then adds a gpu node for the
rk3288 SoC.  This was successfully tested on Radxa Rock2 Square,
Firefly, Veyron Minnie and Jerry boards board using Mali kernel
driver r16p0 and r12p0 user-space binary.

Changes since v1:
- enabled gpu on rk3288-veyron boards

#1614661 — [PATCH v2 1/5] dt-bindings: gpu: add bindings for the ARM Mali Midgard GPU

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

The following optional bindings have been omitted 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

The example has been simplified accordingly.

The compatible string definition has been limited to
"arm,mali-midgard" to avoid checkpatch.pl warnings and to match
what the driver actually expects (as of r16p0 out-of-tree).

Please follow the bindings introduced for the utgard family :
https://patchwork.kernel.org/patch/9553745/

- an entry for each mali-midgard revision, i.e. "arm,mali-t820"
- an entry for each vendor specific wrapping if necessary, i.e. "amlogic,meson-gxm-mali"
- low-case for interrupt names

Please add :
   * Must be one of the following:
      "arm,mali-t820"
   * And, optionally, one of the vendor specific compatible:
      "amlogic,meson-gxm-mali"

with my Ack for the amlogic platform.

"clk_" is redundant. Actually, if there is only 1 clock, then just drop 
names. But there's not at least a core and bus clock?

Is this going to be sufficient vs. operating-points-v2? Or should it be 
a power domain with OPPs?

Drop the '0x'.

Hi Guillaume,

please keep in mind to also add me (as Rockchip maintainer) as recipient in 
further submissions - as also listed by scripts/get_maintainer.pl.


Thanks
Heiko
