Are you sure this is actually necessary?

Every A5XX GPU is using the same value, but i have never tried with
DRM_MSM_INACTIVE_PERIOD.

The suspend here refers to device suspend, not system suspend. Adreno
goes into device suspend every time you stop using it, i.e. after the
rendering is done and there's no more work to do.
I suppose a good test scenario here would be to keep running and closing
kmscube in a rapid fashion and checking if the GPU starts crashing for
unknown reasons (the dmesg would denote that)

The more testing the merrier :)

This was the original patch
https://lore.kernel.org/all/[email protected]/
where the inactive period was increased for a530. I cannot test
suspend on msm8937 yet.
I can check on msm8953 with a506 maybe if a506 works fine with
DRM_MSM_INACTIVE_PERIOD
then a505 would be fine with it also.

I have checked on a505 and a506 with this small script
while true; do kmscube; kill kmscube; done
none of them crashing, so i am going to change it.

Hmm.. not sure if it actually idled when tested in a tight loop.. If you're
running bash, try "while true; do kmscube &; sleep 0.08; pkill -f kmscube; sleep 0.08;done"
