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?
