Hi:
I call the two function , init and enable time irq,but print error information and fail
void __init omap2_gp_timer_init(void)
{
#ifdef CONFIG_LOCAL_TIMERS
if (cpu_is_omap44xx()) {
twd_base = ioremap(OMAP44XX_LOCAL_TWD_BASE, SZ_256);
BUG_ON(!twd_base);
}
#endif
//omap_dm_timer_init();
omap2_gp_clockevent_init();
omap2_gp_clocksource_init();
//omap_dm_timer_enable(gptimer);
//omap_dm_timer_write_counter(gptimer, DM_TIMER_LOAD_MIN);
//omap_dm_timer_start(gptimer);
}
void omap2_gp_timer_enable(void)
{
omap_dm_timer_enable(gptimer);
omap_dm_timer_write_counter(gptimer, DM_TIMER_LOAD_MIN);
omap_dm_timer_start(gptimer);
}
