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
