Hi all,
Here is v2 set of fixes for dra7 ARM architected timer wrap errata i940
where the timer 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
Changes since v1:
- Drop pointless irqflags and IRQF_NOBALANCING as noted by Daniel
