iop: clockevent support
This updates the IOP platform to expose the interrupting timer 0 as a clockevent object. The timer interrupt handler is changed to call the clockevent ->event_handler() instead of timer_tick(), and ->set_next_event() and ->set_mode() operations are added to allow the mode of the timer to be updated (required for ONESHOT/NOHZ mode). Timer 0 must now be properly initialised, which requires a new write_tcr0() function from the mach-specific code. The mode of timer 0 must be read at the start of ->set_mode(), which requires a new read_tmr0() function from the mach- specific code. Initial setup of timer 0 is also rewritten to be more robust. Tested on n2100, compile-tested for all plat-iop machines. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
