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].

FWIW I seem to have reproduced the same behaviour on a different T720 setup, so this may well be more about the GPU than the platform. There doesn't look to be anything obviously wrong with the pagetables, but if I can find some more free time I may have a bit more of a poke around.
