Subject: [PATCH v6 0/6] Allwinner H6 Mali GPU support

Hi,

The Allwinner H6 has a Mali-T720 MP2 which should be supported by
the new panfrost driver. This series fix two issues and introduce the
dt-bindings but a simple benchmark show that it's still NOT WORKING.

I'm pushing it in case someone want to continue the work.

This has been tested with Mesa3D 19.1.0-RC2 and a GPU bitness patch[1].

One patch is from Icenowy Zheng where I changed the order as required
by Rob Herring[2].

Thanks,
Clement
