2012-03-08DMA: PL330: Merge PL330 driver into drivers/dma/Boojin Kim
Currently there were two part of DMAC PL330 driver for support old styled s3c-pl330 which has been merged into drivers/dma/pl330.c driver. Actually, there is no reason to separate them now. Basically this patch merges arch/arm/common/pl330.c into drivers/dma/pl330.c driver and removes useless exported symbol, externed function and so on.

2012-02-21ARM/PCI: Remove ARM's duplicate definition of 'pcibios_max_latency'Myron Stowe
The patch series to re-factor PCI's 'latency timer' setup (re: http://marc.info/?l=linux-kernel&m=131983853831049&w=2) forgot to remove the ARM specific definition of 'pcibios_max_latency' once such had been moved into the pci core resulting in ARM related compile errors - drivers/built-in.o:(.data+0x230): multiple definition of `pcibios_max_latency' arch/arm/common/built-in.o:(.data+0x40c): first defined here make[1]: *** [vmlinux.o] Error 1 In the series, patch 2/16 (commit 168c8619fd8) converted the ARM specific version of 'pcibios_set_master()' to a non-inlined version. This was done in preperation for hosting it up into PCI's core, which was done in patch 10/16 (commit 96c5590058d) of the series (and where the removal of ARM's 'pcibios_max_latency' was overlooked).

Commit 19851c58e680 (sa1111: allow cascaded IRQs to be used by platforms) moved the IRQ definitions to the .c file, and added an irq_base member to the private data structure. The inerrupt demultiplexer uses irq_base, but the interrupt setup code does not. Also, although the commit adds a private data structure to pass this data, it isn't even referenced, resulting in irq_base being zero. We also copied the IRQ numbers from the device info array into the actual devices, resulting in wrong interrupt numbers passed to the sub-devices. The net effect of this is that we always overwrite IRQs 0-54, even if they are allocated elsewhere in the system. Add the code necessary to setup the private irq_base, and use it in the IRQ setup code. Make the SA-1111 probe fail with -EINVAL if there is no platform data provided.

It turns out that the logical CPU mapping is useful even when !CONFIG_SMP for manipulation of devices like interrupt and power controllers when running a UP kernel on a CPU other than 0. This can happen when kexecing a UP image from an SMP kernel. In the future, multi-cluster systems running AMP configurations will require something similar for mapping cluster IDs, so it makes sense to decouple this logic in preparation for this support.

2012-01-06PCI: ARM: convert pcibios_set_master() to a non-inlined functionMyron Stowe
This patch converts ARM's architecture-specific inlined 'pcibios_set_master()' routine to a non-inlined function. This will allow follow on patches to create a generic 'pcibios_set_master()' function using the '__weak' attribute which can be used by all architectures as a default which, if necessary, can then be over- ridden by architecture-specific code. Converting 'pci_bios_set_master()' to a non-inlined function will allow ARM's 'pcibios_set_master()' implementation to remain architecture- specific after the generic version is introduced and thus, not change current behavior. Note that ARM also has a non-inlined 'pcibios_set_master()' that is used if CONFIG_PCI_HOST_ITE8152 is defined. This patch does not change any behavior here either. No functional change.

2011-11-15ARM: gic: allow GIC to support non-banked setupsMarc Zyngier
The GIC support code is heavily using the fact that hardware implementations are exposing banked registers. Unfortunately, it looks like at least one GIC implementation (EXYNOS) offers both the distributor and the CPU interfaces at different addresses, depending on the CPU. This problem is solved by allowing the distributor and CPU interface addresses to be per-cpu variables for the platforms that require it. The EXYNOS code is updated not to mess with the GIC internals while handling interrupts, and struct gic_chip_data is back to being private. The DT binding for the gic is updated to allow an optional "cpu-offset" value, which is used to compute the various base addresses. Finally, a new config option (GIC_NON_BANKED) is used to control this feature, so the overhead is only present on kernels compiled with support for EXYNOS. Tested on Origen (EXYNOS4) and Panda (OMAP4).

Commit "ARM: gic: add irq_domain support" (b49b6ff) breaks SPARSE_IRQ on platforms with GIC. When SPARSE_IRQ is enabled, all NR_IRQS or mach_desc->nr_irqs will be allocated by arch_probe_nr_irqs(). This caused irq_alloc_descs to allocate irq_descs after the pre-allocated space. Make irq_alloc_descs search for an exact irq range and assume it has been pre-allocated on failure. For DT probing dynamic allocation is used. DT enabled platforms should set their nr_irqs to NR_IRQ_LEGACY and have all irq_chips allocate their irq_descs with irq_alloc_descs if SPARSE_IRQ is enabled. gic_init irq_start param is changed to be signed with negative meaning do dynamic Linux irq assigment.

2011-10-31ARM: gic: add OF based initializationRob Herring
This adds ARM gic interrupt controller initialization using device tree data. The initialization function is intended to be called by of_irq_init function like this: const static struct of_device_id irq_match[] = { { .compatible = "arm,cortex-a9-gic", .data = gic_of_init, }, {} }; static void __init init_irqs(void) { of_irq_init(irq_match); } Signed-off-by: Rob Herring <rob.herring@calxeda.com> Reviewed-by: Jamie Iles <jamie@jamieiles.com> Tested-by: Thomas Abraham <thomas.abraham@linaro.org> Acked-by: Grant Likely <grant.likely@secretlab.ca>
2011-10-31ARM: gic: add irq_domain supportRob Herring
Convert the gic interrupt controller to use irq domains in preparation for device-tree binding and MULTI_IRQ. This allows for translation between GIC interrupt IDs and Linux irq numbers. The meaning of irq_offset has changed. It now is just the number of skipped GIC interrupt IDs for the controller. It will be 16 for primary GIC and 32 for secondary GICs.
