Subject[RFC PATCH 0/4] Add support for i.MX8MM GPUs through Etnaviv
Date
From: Frieder Schrempf <frieder.schrempf@kontron.de>

This series contains patches to enable GPU support for the i.MX8MM.
There is currently no upstream support for the display subsystem of
the i.MX8MM, but I have a 5.4-based tree with some ported drivers for
LCDIF, DSIM bridge, etc. (see [1]) which I used to test the GPU with
glmark2.

I'm posting this as an RFC for now, as I'm not feeling confident of
all of the changes. Especially patch 1 seems a bit like a hack. Maybe
someone can help me understand the underlying problem and/or come up
with a better fix.

Frieder Schrempf (4):
drm/etnaviv: Prevent IRQ triggering at probe time on i.MX8MM
drm/etnaviv: Fix error path in etnaviv_gpu_clk_enable()
drm/etnaviv: Change order of enabling clocks to fix boot on i.MX8MM
arm64: dts: imx8mm: Add GPU nodes for 2D and 3D core using Etnaviv
