I wonder if the panfrost folks can reuse this for the issue discussed
over at:

https://lore.kernel.org/r/cover.1600213517.git.robin.murphy@xxxxxxx

However, Sai, your email setup went wrong when you posted this so you
probably need to repost now that you have that fixed.


I have sent a v5 [1] now since I had to drop cleanup of blank lines
as Robin said it was intentional and also had to rebase over new
gpu changes since it moves pretty fast.

Thanks,
