2008-08-07[ARM] Move include/asm-arm/arch-* to arch/arm/*/include/machRussell King30-24/+1141
This just leaves include/asm-arm/plat-* to deal with. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-08-07[ARM] Eliminate useless includes of asm/mach-types.hRussell King1-1/+0
There are 43 includes of asm/mach-types.h by files that don't reference anything from that file. Remove these unnecessary includes. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-08-03[ARM] Fix explicit asm(-arm)?/arch-foo referencesRussell King9-23/+23
No file should be explicitly referencing its own platform headers by specifying an absolute include path. Fix these paths to use standard <asm/arch/...> includes. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-04-25ns9xxx: fix sparse warningUwe Kleine-König1-1/+1
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-König1-0/+5
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-König1-6/+9
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-König1-12/+18
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-König1-1/+39
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-König12-174/+294
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-König1-12/+16
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-König1-1/+1

2008-03-31ns9xxx: move registration of serial8250 to a dedicated fileUwe Kleine-König4-58/+76
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-König1-1/+1
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>
2007-10-13[ARM] 4595/1: ns9xxx: define registers as void __iomem * instead of volatile u32Uwe Kleine-König4-61/+85
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>
2007-10-13[ARM] 4594/1: ns9xxx: use the new gpio functionsUwe Kleine-König1-6/+6
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.

2007-10-13[ARM] 4590/1: ns9xxx: add gpio handling functionsUwe Kleine-König2-1/+185
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>
2007-10-13[ARM] 4589/1: ns9xxx: acknowledge IRQ_EXT2 in the demux routine for FPGA irqsUwe Kleine-König1-2/+7
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>
2007-10-13[ARM] 4545/1: ns9xxx: simplify irq ack'ingUwe Kleine-König2-33/+14
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-König1-2/+1
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.
