Change to use linux/semaphore.h Signed-off-by: Matthew Wilcox <willy@linux.intel.com>

2008-04-25ns9xxx: fix sparse warningUwe Kleine-König
The actual warning is arch/arm/mach-ns9xxx/irq.c:65:6: warning: symbol 'handle_prio_irq' was not declared. Should it be static? Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
2008-04-25ns9xxx: check for irq lockupsUwe Kleine-König
When I copy-adapted handle_level_irq I skipped note_interrupt because I considered it unimportant. If I had understand its importance I would have saved myself some ours of debugging. Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
2008-04-25ns9xxx: fix handle_prio_irq to unmask irqs with lower priorityUwe Kleine-König
When an irq is reported all lower prio irqs are masked until the current irq is acked. So never leave handle_prio_irq without acking. desc->status & IRQ_INPROGRESS should never become true because the current irq is masked until it is acked, too.

2008-03-31ns9xxx: add support for irq priorisationUwe Kleine-König
prio2irq(0) is the highest prioritized interrupt. For now there is no binary change intended. If you intend to change the priorisation, you have to assert: ∀ x ∈ {0, 1, ⋯ 31}: (irq2prio ∘ prio2irq)(x) = x Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
2008-03-31ns9xxx: make use of the chip's irq priorisationUwe Kleine-König
The irq controller automatically masks the current and all lower prioritised tasks until the current irq is acked. Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
2008-03-31ns9xxx: prepare for adding support for Digi ns921x processorsUwe Kleine-König
The hardware team changed some things that were taken as being common to all ns9xxx processors up to now. This patch addresses: - irqs: s/IRQ_/IRQ_NS9360_/ - system module registers: some registers are still general, their definition lives now in include/asm-arm/arch-ns9xxx/regs-sys-common.h. The ns9360 specific ones are in .../regs-sys-ns9360.h As a result ns9360_systemclock cannot be static inline any more as its definition needs regs-sys-ns9360.h. This becomes a real problem when adding support for ns9215 as this will need regs-sys-ns9215.h and including both files will not work. For the same reason ns9360_reset() is now non-inline and gpio functions live in their own file. - register mapping: s/ns9xxx_map_io/ns9360_map_io/ - timer registers: move time.c to time-ns9360.c; s/ns9xxx_timer/ns9360_timer/ Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
2008-03-31ns9xxx: introduce a config variable for the cc9p9360 moduleUwe Kleine-König
Moreover now it's the module that selects the processor, and not the machine anymore. Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
2008-03-31ns9xxx: use default text offsetUwe Kleine-König
Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
2008-03-31ns9xxx: move registration of serial8250 to a dedicated fileUwe Kleine-König
Now the needed structs are allocated dynamically from __init code reducing memory usage if the kernel runs on a board different from a9m9750dev. Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
2008-03-08[ARM] 4851/1: ns9xxx: fix size of gpioresUwe Kleine-König
GPIO_MAX is the number of the last gpio, not the number of gpios. So the bitmap must provide GPIO_MAX + 1 bits. Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-10-12[ARM] 4595/1: ns9xxx: define registers as void __iomem * instead of volatile u32Uwe Kleine-König
As a consequence registers are now accessed with __raw_{read,write}[bl]. Signed-off-by: Uwe Kleine-König <ukleinek@informatik.uni-freiburg.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-10-12[ARM] 4594/1: ns9xxx: use the new gpio functionsUwe Kleine-König
Up to now only board-a9m9750dev.c used GPIOs. It just wrote directly into the corresponding registers. Now it properly reserves the gpio and uses the API function to configure it.

2007-10-12[ARM] 4590/1: ns9xxx: add gpio handling functionsUwe Kleine-König
This implementation conforms to the general GPIO API introduced in 2.6.21. This patch was signed-of by David Brownell before I exported the functions using EXPORT_SYMBOL. Signed-off-by: Uwe Kleine-König <ukleinek@informatik.uni-freiburg.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-10-12[ARM] 4589/1: ns9xxx: acknowledge IRQ_EXT2 in the demux routine for FPGA irqsUwe Kleine-König
The FPGA on the a9m9750dev board interrupts the CPU via EXT2. So to acknowledge any FPGA interrupt IRQ_EXT2 must be acknowledged. Signed-off-by: Uwe Kleine-König <ukleinek@informatik.uni-freiburg.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-10-12[ARM] 4545/1: ns9xxx: simplify irq ack'ingUwe Kleine-König
Now the drivers are responsible to clear the irq in the respective device, which seems to be the normal thing to do. So the ack'ing of the timer irq moved to time.c. Signed-off-by: Uwe Kleine-König <ukleinek@informatik.uni-freiburg.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-07-20[ARM] 4487/1: ns9xxx: complete definition of GPIO related registersUwe Kleine-König
I changed the naming to be more obvious---unfortunately the HRM doesn't specify these. Moreover the numbering is changed to be zero indexed as this is more natural. Adjust all callers.
