517 is EPROBE_DEFER, which implies it's waiting for the relevant clock provider to show up. I see from patch #2 that SCMI is involved, so I'd check that that's working and you have CONFIG_COMMON_CLOCK_SCMI enabled.

Robin,

Many thx!
Indeed issue was with SCMi CLK.
Now i see:

[    3.092350] panfrost fde60000.gpu: clock rate = 594000000
[    3.092906] panfrost fde60000.gpu: bus_clock rate = 500000000
[    3.138340] panfrost fde60000.gpu: clock rate = 594000000
[    3.138904] panfrost fde60000.gpu: bus_clock rate = 500000000
[    3.171244] panfrost fde60000.gpu: clock rate = 594000000
[    3.171888] panfrost fde60000.gpu: bus_clock rate = 500000000

good.

(unfortunately mesa 21.3.4 still goes with llvmpipe but this seems to be other issue i need to investigate)

thx again!
