[PATCH 0/8] Add Allwinner H6 Mali Midgard gpu node

[PATCH 0/8] Add Allwinner H6 Mali Midgard gpu node

[Clément Péron]

Hi,

The Allwinner H6 has a Mali-T720 MP2. The drivers are
out-of-tree so this serie only introduce the dt-bindings.

The first patch is from Neil Amstrong and has been already
merged in linux-amlogic. It is required for this serie.

The second patch is from Icenowy Zheng where I changed the
order has required by Rob Herring.
See: https://patchwork.kernel.org/patch/10699829/

The GPU opp table is taken from Jernej Škrabec's patch
on LibreELEC.tv.

Thanks,
Clement

[PATCH 1/8] dt-bindings: gpu: mali-midgard: Add resets property

[Clément Péron]

From: Neil Armstrong <narmstrong@baylibre.com>

The Amlogic ARM Mali Midgard requires reset controls to power on and
software reset the GPU, adds these as optional in the bindings.

Yes you're right clocks are also required for the H6.
