Hello,

I wrote codes for a custom hardware driver, which requests IRQ using GPIO 317 (CAN0_DIN), but an error occured when running the function:

request_threaded_irq()

The error message is:

irq: IRQ300: trimming hierarchy from :pmc@c360000

Could anyone teach me how to fix this? Thanks!

hello pandako7,

this messages belong to pr_info which isn’t error logs.
may I know what’s the use-case, could you please attach complete kernel logs for reference, thanks

Thanks! I found that it’s GPIO not working. This does nothing with irq. Thank you for your clarification. I will post another topic later.
