* clocksource: Kona: Print warning rather than panicTim Kryger2014-02-061-26/+28
| | | | | | | | | | | | | | | Since there may be other clocksources available, this driver should not trigger a panic simply because it can not determine the frequency of an external clock. This change refactors the driver to allow a warning to be printed in this case instead.

To avoid such calls the timer input frequency is stored in the driver's data struct which makes it accessible to the driver in any context.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit: 65cd4f6 ("arch_timer: Move to generic sched_clock framework") added code to register the arch_sys_counter in arch_timer_register(), but it is already registered in arch_counter_register(). This results in the timer being added to the clocksource list twice, therefore causing an infinite loop in the list. Remove the duplicate registration and register the scheduler clock after the original registration instead. This fixes a hang during boot on Tegra114 (Cortex-A15).
