33a5b8838e ARM: pxa: fix broken isa interrupts for zeus and viper
Commit "ARM: pxa: arbitrarily set first interrupt number" broke viper
and zeus boards which still refer to PXA_ISA_IRQ() macro. Redefine
the macro, which declares the legacy interrupts from 0 to 15.

3ad32229be ARM: pxa: arbitrarily set first interrupt number
As IRQ0, the legacy timer interrupt  should not be used as an interrupt
number, shift the interrupts by a fixed number.

As we had in a special case a shift of 16 when ISA bus was used on a
PXA, use that value as the first interrupt number, regardless of ISA or
not.

49ea7fc094 ARM: pxa: remove pxa95x support
PXA95x isn't widely used. And it adds the effort on supporting
multiple platform. So remove it.

The assumption is that nobody will miss this support. If you are
reading this text because you actually require pxa95x support on
a new kernel, we can work out a way to revert this patch or add
support to the mmp platform.

87c49e2057 ARM: pxa: use chained interrupt for GPIO0 and GPIO1
GPIO0 and GPIO1 are linked to unique interrupt line in PXA series,
others are linked to another interrupt line. All GPIO are linked to one
interrupt line in MMP series.

Since gpio driver is shared between PXA series and MMP series, define
GPIO0 and GPIO1 as chained interrupt chip. So we can move out gpio code
from irq.c to gpio-pxa.c.

7db6a7fa09 ARM: pxa: convert incorrect IRQ_TO_IRQ() to irq_to_gpio()
This fixes the failure to register the IRQ_RTCAlrm alarm as a wakeup
event.  It is misinterpreted as a gpio irq not a PWER bitmask. Fixed
this by converting the incorrect IRQ_TO_IRQ() to a correct version of
irq_to_gpio().

00dd8027b9 [ARM] locomo: remove unused IRQs and avoid unnecessary cascade
IRQ_LOCOMO_* are never used elsewhere, remove these definitions. As well
as the cascade of these IRQs. IRQ_LOCOMO_*_BASE changed to IRQ_LOCOMO_*.

IRQ_LOCOMO_LT and IRQ_LOCOMO_SPI are likely to be used in a same way as
IRQ_LOCOMO_KEY.

IRQ_LOCOMO_GPIO and the demultiplex handler should really be living
somewhere else.

So, again against latest pxa-linux-2.6/devel, with the following
changes:

 * Move to __raw_readl/__raw_writel for FPGA/CPLD register access
 * Change Toppoly LCD config to be selectable at run time rather than
   compile time.
 * Remove currently unused irq device suspend/resume functions.
 * Strip out unnecessary/duplicated #includes.
 * Some code style cleanups.

a01bd58449 [ARM] pxa: allow IRQ_BOARD_END to be customized and make zylonite to use it
The default value is 16 IRQs. Zylonite needs 32, ASIC3 based boards need 70.

My problem is still that due to the way IRQ_GPIO is hardcoded, ASIC3 based boards
need 70 IRQs starting at IRQ_BOARD_START. If I define ASIC3 IRQs similar to LoCoMo
or SA1111, things break as soon as something selects PXA_HAVE_BOARD_IRQS.
Increasing the default number of board IRQs to 70 instead doesn't seem very nice.
