H A D | rtc_cmos_setup.c | diff e517881e427757afc3cce6d76173b1d898b30ab3 Thu Jun 12 01:04:31 CEST 2008 Anton Vorontsov <avorontsov@ru.mvista.com> powerpc: rtc_cmos_setup: assign interrupts only if there is i8259 PIC
i8259 PIC is disabled on MPC8610HPCD boards, thus currently rtc-cmos driver fails to probe.
To fix the issue, we lookup the device tree for "chrp,iic" and "pnpPNP,000" compatible devices, and if not found we do not assign RTC IRQ and assuming that i8259 was disabled.
Though this patch fixes RTC on some boards (and surely should not break any other), the whole approach is still broken. We can't easily fix this though, because old device trees do not specify i8259 interrupts for the cmos rtc node.
