Hello guys,
Hello Hauke,
Sorry for the amount of mails.
So in I patched the kernel to be more specific on PMU error messages, since it
seems something is fundamentally wrong here:
the system panics like

Secondly, I am encountering some issues in
int __init lq_gptu_init(void)
...
infact vendor firmware is not using
as I get a data abort at line 798 which reads:
timer_dev.number_of_timers = GPTU_ID_CFG * 2;
and looking at the vendor firmware, they do something like
timer_dev.number_of_timers = 3 * 2;
Where may I check for wrong things?
Thanks!!
Enrico
