2011-10-28sh: intc: Add IRQ trigger bit field checkMagnus Damm1-2/+7
R-Mobile SoCs such as sh73a0 include PINT blocks in INTC that come with 2-bit IRQ trigger support. Add code to make sure the bit width is checked so 4-bit only modes like for instance EDGE_BOTH will fail for PINT.

2011-03-23sh: Use struct syscore_ops instead of sysdevsRafael J. Wysocki2-49/+47
Convert the SuperH clocks framework and shared interrupt handling code to using struct syscore_ops instead of a sysdev classes and sysdevs for power managment. This reduces the code size significantly and simplifies it. The optimizations causing things not to be restored after creating a hibernation image are removed, but they might lead to undesirable effects during resume from hibernation (e.g. the clocks would be left as the boot kernel set them, which might be not the same way as the hibernated kernel had seen them before the hibernation). This also is necessary for removing sysdevs from the kernel entirely in the future. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-01-19sh: update INTC to clear IRQ sense valid flagMagnus Damm1-2/+4
Clear the valid flag is in the INTC code. Without this fix bit 7 of the sense register is mistakenly set. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-12-24sh: intc: Initialize radix tree gfp mask explicitly.Paul Mundt1-0/+1
Presently the root node is initialized by way of kzalloc on the parent data structure, which by chance happens to do the bulk of what an explicit initialization does with GFP_NOWAIT semantics. This however is more by luck than by design, and as we ideally want to permit radix node allocations access to the emergency pools anyways, add in the proper initializer with the desired mask. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-11-15sh: intc: Fix up build failure introduced by radix tree changes.Paul Mundt1-1/+1
The radix tree retry logic got a bit of an overhaul and subsequently broke the virtual IRQ subgroup build. Simply switch over to radix_tree_deref_retry() as per the filemap changes, which the virq lookup logic was modelled after in the first place. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-11-01sh: intc: Update for single IRQ reservation helper.Paul Mundt2-2/+2
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-28sh: intc: switch irq_desc iteration to new active IRQ iterator.Paul Mundt1-8/+2
There's no need to iterative over every single irq_desc when we can already work out which IRQs have a backing descriptor via the shiny new for_each_active_irq(). Switch to that instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-27sh: intc: irq_data conversion.Paul Mundt4-40/+68
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-26sh: Switch dynamic IRQ creation to generic irq allocator.Paul Mundt2-75/+9
Now that the genirq code provides an IRQ bitmap of its own and the necessary API to manipulate it, there's no need to keep our own version around anymore. In the process we kill off some unused IRQ reservation code, with future users now having to tie in to the genirq API as normal. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-26sh: Sanitize sparse irqThomas Gleixner2-19/+14
Switch over to the new allocator functions. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-06sh: intc: Fix build with IRQ balancing disabled.Paul Mundt1-4/+5
The balancing stubs obviously need to be static inline.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-06sh: intc: Add missing files.Paul Mundt2-0/+40
The Kconfig and Makefile were overlooked, add those in now to improve odds of building. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-05sh: intc: Split up the INTC code.Paul Mundt10-0/+2047
This splits up the sh intc core in to something more vaguely resembling a subsystem. Most of the functionality was alread fairly well compartmentalized, and there were only a handful of interdependencies that needed to be resolved in the process. This also serves as future-proofing for the genirq and sparseirq rework, which will make some of the split out functionality wholly generic, allowing things to be killed off in place with minimal migration pain.
