devel-stable
2012-01-30ARM: picoxcell: remove mach/irqs.hJamie Iles
picoxcell uses SPARSE_IRQ which means we don't need a mach/irqs.h anymore so kill it off. Signed-off-by: Jamie Iles <jamie@jamieiles.com> Signed-off-by: Rob Herring <rob.herring@calxeda.com>
2012-01-30ARM: highbank: select SPARSE_IRQ and remove irqs.hRob Herring
irqs.h is optional now for SPARSE_IRQ, so select it and remove mach/irqs.h from highbank. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
2012-01-30ARM: only include mach/irqs.h for !SPARSE_IRQRob Herring
Make mach/irqs.h optional for SPARSE_IRQ. With this change mach/irqs.h can be removed by converting platforms over to sparse irq. Platforms either need to set nr_irqs in their machine desc or all irqchips used by a platform need to allocate their irq_descs. There cannot be a mixture. Once this is done, the platforms can select SPARSE_IRQ. shmobile does the latter, and mmp and pxa do the former. Signed-off-by: Rob Herring <rob.herring@calxeda.com>

2012-01-25ARM: shmobile: remove NR_IRQSRob Herring
Remove NR_IRQS and explicitly include mach/irqs.h as needed. shmobile properly allocates irq_descs for each irqchip, so setting .nr_irqs for each machine is not needed. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
2012-01-25ARM: pxa: remove NR_IRQSRob Herring
Remove NR_IRQS and add a per machine .nr_irqs setting. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
2012-01-25ARM: mmp: remove NR_IRQSRob Herring
Remove NR_IRQS and add a per machine .nr_irqs setting. Clean-up namespace replacing usage of IRQ_BOARD_START with MMP_NR_IRQS. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
2012-01-25sh: intc: remove dependency on NR_IRQSRob Herring
SH intc has a compile time dependency on NR_IRQS. Make this dependency a local define so that shmobile (and ARM in general) can have run-time NR_IRQS setting. Signed-off-by: Rob Herring <rob.herring@calxeda.com>

2012-01-25irq: make SPARSE_IRQ an optionally hidden optionRob Herring
On ARM, we don't want SPARSE_IRQ to be a user visible option. Make SPARSE_IRQ visible based on MAY_HAVE_SPARSE_IRQ instead of depending on HAVE_SPARSE_IRQ. With this, SPARSE_IRQ is not visible on C6X and ARM.

2012-01-25ARM: 7300/1: realview: fix definition of GPIO0 interrupt on PB1176 to match TRMWill Deacon
Currently, -1 is used as the GPIO0 interrupt on realview PB1176 and an AMBA device is registered with this parameter. With the pending NO_IRQ cleanup, this will lead to a warning at boot time, since -1 is obviously broken. This patch updates the interrupt used for GPIO0 to match that specified by the TRM. Unfortunately, it's not clear how to trigger this interrupt so we trust that the documentation is correct.
