some drivers write to this register upon initialization. This can cause

Hello Kumar,
The previous series scattered a bit, so I gathered it again.
I've found MPC8572DS board to test RTC quirk changes that I've made
for MPC8610HPCD, and it appears that without the change RTC does not
work on MPC8572DS, too.
So, the first patch actually fixes it for MPC8572DS, and
This patch fixes RTC on MPC8572DS boards: dummy read helps only when
reading at the end of the bridge's memory (i.e. outside of behind the
bridge devices' assigned regions).
With this change the quirk also makes RTC work on MPC8610HPCD, so it's
unlikely that this will break MPC8641HPCN or
- Get rid of uses_fsl_uli_m1575, it does not scale for all cases.
Instead, let's explicitly use machine_is() for each fixup.
- Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with
machine_is(). One step closer to multiplatform kernels.
- Actually use fsl_uli1575 on MPC8610HPCD,
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
The ULI Super South Bridge contains ISA bridge to the legacy
devices, such as Super IO mouse/keyboard/floppy disk controllers,
parallel port, i8259 interrupt controller and so on.
i8259 is disabled on the MPC8610HPCD, and other peripherals are not
traced out. So we use only RTC.
