2012-05-21MIPS: lantiq: convert dma to platform driverJohn Crispin
Add code to make the dma driver load as a platform device from the devicetree. Signed-off-by: John Crispin <blogic@openwrt.org> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/3824/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2012-05-21MIPS: lantiq: implement support for clkdev apiJohn Crispin
This patch unifies all clock generation and gating code into one file. All drivers will now be able to request their clocks via their device. This patch also adds support for the clockout feature, which allows clock generation on external pins. Support for COMMON_CLK will be provided in the next series.

2012-05-21MIPS: lantiq: drop ltq_gpio_request() and gpio_to_irq()John Crispin
As part of the conversion to OF we also implement pinctrl drivers. Previously we used ltq_gpio_request() to set pinmuxing. This is now obselete and we can hence drop the function. Additionally we remove gpio_to_irq() from the gpio driver and move it to a header file.

2012-05-21OF: MIPS: lantiq: implement irq_domain supportJohn Crispin
Add support for irq_domain on lantiq socs. The conversion is straight forward as the ICU found inside the socs allows the usage of irq_domain_add_linear. Harware IRQ 0->7 are the generic MIPS IRQs. 8->199 are the Lantiq IRQ Modules. Our irq_chip callbacks need to substract 8 (MIPS_CPU_IRQ_CASCADE) from d->hwirq to find out the correct offset into the Interrupt Modules register range.

2012-05-21xen/smp: unbind irqworkX when unplugging vCPUs.Konrad Rzeszutek Wilk
The git commit 1ff2b0c303698e486f1e0886b4d9876200ef8ca5 "xen: implement IRQ_WORK_VECTOR handler" added the functionality to have a per-cpu "irqworkX" for the IPI APIC functionality. However it missed the unbind when a vCPU is unplugged resulting in an orphaned per-cpu interrupt line for unplugged vCPU: 30: 216 0 xen-dyn-event hvc_console 31: 810 4 xen-dyn-event eth0 32: 29 0 xen-dyn-event blkif - 36: 0 0 xen-percpu-ipi irqwork2 - 37: 287 0 xen-dyn-event xenbus + 36: 287 0 xen-dyn-event xenbus NMI: 0 0 Non-maskable interrupts LOC: 0 0 Local timer interrupts SPU: 0 0 Spurious interrupts Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
2012-05-21ARM: dma-mapping: use PMD size for section unmapVitaly Andrianov
The dma_contiguous_remap() function clears existing section maps using the wrong size (PGDIR_SIZE instead of PMD_SIZE). This is a bug which does not affect non-LPAE systems, where PGDIR_SIZE and PMD_SIZE are the same. On LPAE systems, however, this bug causes the kernel to hang at this point. This fix has been tested on both LPAE and non-LPAE kernel builds. Signed-off-by: Vitaly Andrianov <vitalya@ti.com> Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>
2012-05-21ARM: integrate CMA with DMA-mapping subsystemMarek Szyprowski
This patch adds support for CMA to dma-mapping subsystem for ARM architecture. By default a global CMA area is used, but specific devices are allowed to have their private memory areas if required (they can be created with dma_declare_contiguous() function during board initialisation). Contiguous memory areas reserved for DMA are remapped with 2-level page tables on boot. Once a buffer is requested, a low memory kernel mapping is updated to to match requested memory access type. GFP_ATOMIC allocations are performed from special pool which is created early during boot. This way remapping page attributes is not needed on allocation time. CMA has been enabled unconditionally for ARMv6+ systems.

2012-05-21drivers: add Contiguous Memory AllocatorMarek Szyprowski
The Contiguous Memory Allocator is a set of helper functions for DMA mapping framework that improves allocations of contiguous memory chunks. CMA grabs memory on system boot, marks it with MIGRATE_CMA migrate type and gives back to the system. Kernel is allowed to allocate only movable pages within CMA's managed memory so that it can be used for example for page cache when DMA mapping do not use it. On dma_alloc_from_contiguous() request such pages are migrated out of CMA area to free required contiguous block and fulfill the request. This allows to allocate large contiguous chunks of memory at any time assuming that there is enough free memory available in the system. This code is heavily based on earlier works by Michal Nazarewicz.

2012-05-21ARM: dma-mapping: add support for IOMMU mapperMarek Szyprowski
This patch add a complete implementation of DMA-mapping API for devices which have IOMMU support. This implementation tries to optimize dma address space usage by remapping all possible physical memory chunks into a single dma address space chunk. DMA address space is managed on top of the bitmap stored in the dma_iommu_mapping structure stored in device->archdata. Platform setup code has to initialize parameters of the dma address space (base address, size, allocation precision order) with arm_iommu_create_mapping() function. To reduce the size of the bitmap, all allocations are aligned to the specified order of base 4 KiB pages. dma_alloc_* functions allocate physical memory in chunks, each with alloc_pages() function to avoid failing if the physical memory gets fragmented. In worst case the allocated buffer is composed of 4 KiB page chunks. dma_map_sg() function minimizes the total number of dma address space chunks by merging of physical memory chunks into one larger dma address space chunk. If requested chunk (scatter list entry) boundaries match physical page boundaries, most calls to dma_map_sg() requests will result in creating only one chunk in dma address space. dma_map_page() simply creates a mapping for the given page(s) in the dma address space. All dma functions also perform required cache operation like their counterparts from the arm linear physical memory mapping version.

2012-05-21ARM: dma-mapping: implement dma sg methods on top of any generic dma opsMarek Szyprowski
This patch converts all dma_sg methods to be generic (independent of the current DMA mapping implementation for ARM architecture). All dma sg operations are now implemented on top of respective dma_map_page/dma_sync_single_for* operations from dma_map_ops structure. Before this patch there were custom methods for all scatter/gather related operations. They iterated over the whole scatter list and called cache related operations directly (which in turn checked if we use dma bounce code or not and called respective version). This patch changes them not to use such shortcut. Instead it provides similar loop over scatter list and calls methods from the device's dma_map_ops structure. This enables us to use device dependent implementations of cache related operations (direct linear or dma bounce) depending on the provided dma_map_ops structure.

2012-05-21ARM: dma-mapping: remove offset parameter to prepare for generic dma_opsMarek Szyprowski
This patch removes the need for the offset parameter in dma bounce functions. This is required to let dma-mapping framework on ARM architecture to use common, generic dma_map_ops based dma-mapping helpers. Background and more detailed explaination: dma_*_range_* functions are available from the early days of the dma mapping api. They are the correct way of doing a partial syncs on the buffer (usually used by the network device drivers). This patch changes only the internal implementation of the dma bounce functions to let them tunnel through dma_map_ops structure. The driver api stays unchanged, so driver are obliged to call dma_*_range_* functions to keep code clean and easy to understand. The only drawback from this patch is reduced detection of the dma api abuse. Let us consider the following code: dma_addr = dma_map_single(dev, ptr, 64, DMA_TO_DEVICE); dma_sync_single_range_for_cpu(dev, dma_addr+16, 0, 32, DMA_TO_DEVICE); Without the patch such code fails, because dma bounce code is unable to find the bounce buffer for the given dma_address. After the patch the above sync call will be equivalent to: dma_sync_single_range_for_cpu(dev, dma_addr, 16, 32, DMA_TO_DEVICE); which succeeds. I don't consider this as a real problem, because DMA API abuse should be caught by debug_dma_* function family. This patch lets us to simplify the internal low-level implementation without chaning the driver visible API.

2012-05-21sh: Kill off machvec IRQ hinting.Paul Mundt
Everything is using sparseirq these days, so we have no need to arbitrarily size nr_irqs ahead of time. The legacy IRQ pre-allocation likewise has no meaning for us, so that's killed off too. We now depend on nr_irqs expansion by the generic hardirq layer instead. It's also worth noting that the majority of boards had completely bogus values for their nr_irqs relative to their CPU and configurations, so this ends up correcting behaviour for quite a few platforms.
