Hi Sibi,


Bjorn asked me to give this patch a whirl, and I have to say, I like it
but I'm not sure if I'm missing a dependency somewhere...


In 5.8.0-rc4, I'm seeing a couple probe defers

[    0.131341] cpu cpu0: _allocate_opp_table: Error finding interconnect
paths: -517

[    0.132694] cpu cpu4: _allocate_opp_table: Error finding interconnect
paths: -517

And then a bit later on,

[    0.625837] cpu cpu0: failed to get clock: -2


If these aren't anything to worry about, you can throw my Tested-by on
