So it was already included in 4.19, I don't need to patch it, that is
good :-). Sorry I am still not clear how to stop that error message of
"rtc rtc0: Timeout trying to get valid LPSRT Counter read", the
message says "To avoid kernel hangs, put in timeouts", I am running
kernel 4.19.75 on iMX6, where should I put in timeouts?

Thank you very much for your kind help.

Kind regards,
