Hi Rajendra,

After applying 2,3 and 4/5 patches on linaro-integration v5.8-rc2 I see
below messages on db845:

qcom-venus aa00000.video-codec: dev_pm_opp_set_rate: failed to find
current OPP for freq 533000097 (-34)

^^^ This one is new.

I was hoping to be able to reproduce this on the 845 mtp (I don't have
a db845), but I can;t seem to get venus working on mainline [1]
(neither with linux-next, nor with linaro integration)
Do you know if I might be missing some fix?


qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x30000

^^^ and this message is annoying, can we make it pr_debug in rpmh?

Sure, I'll send a patch for that and see what the rpmh owners have to say.
