2015-01-27ARM: pxa: fix broken isa interrupts for zeus and viperRobert Jarzmik1-0/+1
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.

2014-12-26ARM: pxa: arbitrarily set first interrupt numberRobert Jarzmik1-7/+2
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.

2012-11-15ARM: pxa: remove pxa95x supportHaojian Zhuang1-1/+0
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.

2011-11-14ARM: pxa: rename NR_BUILTIN_GPIOHaojian Zhuang1-2/+2
NR_BUILTIN_GPIO is both defined in arch-pxa and arch-mmp. Now replace it with PXA_NR_BUILTIN_GPIO and MMP_NR_BUILTIN_GPIO. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
2011-11-14ARM: pxa: use chained interrupt for GPIO0 and GPIO1Haojian Zhuang1-3/+1
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.

2011-04-13ARM: pxa: convert incorrect IRQ_TO_IRQ() to irq_to_gpio()Eric Miao1-3/+0
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(). Reported-by: Nick Bane <nickbane1@gmail.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>

2010-03-02[ARM] locomo: remove unused IRQs and avoid unnecessary cascadeEric Miao1-28/+3
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.

2010-03-02[ARM] locomo: avoid unnecessary cascaded keyboard IRQEric Miao1-2/+1
It is not necessary and is over-complicated for IRQ_LOCOMO_KEY to be a cascaded IRQ of IRQ_LOCOMO_KEY_BASE. Removed and introduced locomokbd_{open,close} for masking/unmasking of the keyboard IRQ. Signed-off-by: Eric Miao <eric.y.miao@gmail.com>

2009-06-05[ARM] pxa: allow IRQ_BOARD_END to be customized and make zylonite to use itPhilipp Zabel1-5/+11
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.
