Hello all,
I did run some benchmark on i.MX8MM GPU and I have some concerns on the
differences between mainline Linux/etnaviv/Mesa and the proprietary NXP/Vivante
solution.
The tests were executed comparing glmark2 results between a mainline kernel
(6.9.0-rc6) running Mesa 24.0.3 and NXP

Having conditional around the of_node pointer of the drm_bridge structure
is not necessary, since drm_bridge structure always has the of_node as its
member.
Let's drop the conditional to get a better looks, please also note that
this is following the already accepted commitments. see commit
