I have created v2 of that fix and it got merged via Chanwoo's tree, the commit 4fc9a0470d2dc37028 https://lkml.org/lkml/2020/7/10/1048
That commit switched the driver default mode from 'irq driven' to new devfreq monitoring mechanism. Furthermore, when the driver is built as a module, you can try to use the 'irq mode', but for this you would need the DT IRQs description (this $subject tries to remove).
I would like to keep this IRQ mode for experimentation, as I described in answers to Bartek's questions: https://lkml.org/lkml/2020/7/14/315
Unfortunately, I am quite busy and won't make any progress before the LPC.
Regards, Lukasz
