Fine, so simply reverse the logic and drop the "arm,sp804-clock*"
properties. Something like:
if (has_timint1) {
evtoffs = TIMER_1_BASE;
irq = irq_of_parse_and_map(np, 1);
srcoffs = TIMER_2_BASE;
} else (has_timint2) {
evtoffs = TIMER_2_BASE;
irq = irq_of_parse_and_map(np, 2);
srcoffs = TIMER_1_BASE;
} else {
can't be clockevent, sorry
}
Hope it makes clear what I'd expect from the driver.
Pawe?
