We should not trace digicolor_timer_sched_read() function. Fix this by adding the notrace attribute to this function.

clockevents/drivers/digicolor: Migrate to new 'set-state' interface 2015-08-10T09:40:45+00:00 Viresh Kumar viresh.kumar@linaro.org 2015-06-18T10:54:46+00:00 e0d1ca332c1e91febd0de0ef69a45957cdc39fd8 Migrate digicolor driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED.

clocksource: Driver for Conexant Digicolor SoC timer 2015-01-29T13:02:15+00:00 Baruch Siach baruch@tkos.co.il 2015-01-26T18:35:18+00:00 9b8bb7736b78e954044e12b94a2b16aafb0ee0e3 Add clocksource driver to the Conexant CX92755 SoC, part of the Digicolor SoCs series. Hardware provides 8 timers, A to H. Timer A is dedicated to a future watchdog driver so we don't use it here. Use timer B for sched_clock, and timer C for clock_event.
