Hi all,
Here are fixes for dra7 ARM architected timer wrap errata i940 where it
fails to wrap after 388 days. The workaround is to use two dmtimers as
the local timers instead.
Note that these patches depend on timer posted mode fixes series
"[PATCH 0/3] Fixes for timer-ti-dm systimer posted mode" for the write
status register check fix. Also the spurious timer interrupt fix is
good to have from that series.
Regards,
Tony
