| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the r4k timer is registered no matter what, bump the rating of the Alchemy 32kHz timer so that it gets used when it is working, and fall back on the r4k when it isn't. This fixes a timer-related hang on platform with a working 32kHz timer (the better rated c0 timer stops while executing 'wait' leading to (almost) eternal sleep) and an oops on boot on platforms without a working 32kHz timer (due to double registration of the r4k timer).

* | MIPS: drivers: remove __dev* attributes.Greg Kroah-Hartman2013-01-0323-65/+61
|/ | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

The most important one is probably, that dma-debug now warns if a dma-handle is not checked with dma_mapping_error by the device driver. This requires minor changes to some architectures which make use of dma-debug. Most of these changes have the respective Acks by the Arch-Maintainers. Besides that there are updates to the AMD IOMMU driver for refactor the IOMMU-Groups support and to make sure it does not trigger a hardware erratum. The OMAP changes (for which I pulled in a branch from Tony Lindgren's tree) have a conflict in linux-next with the arm-soc tree. The conflict is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in the arm-soc tree. It is safe to delete the file too so solve the conflict. Similar changes are done in the arm-soc tree in the common clock framework migration. A missing hunk from the patch in the IOMMU tree will be submitted as a seperate patch when the merge-window is closed." * tag 'iommu-updates-v3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (29 commits) ARM: dma-mapping: support debug_dma_mapping_error ARM: OMAP4: hwmod data: ipu and dsp to use parent clocks instead of leaf clocks iommu/omap: Adapt to runtime pm iommu/omap: Migrate to hwmod framework iommu/omap: Keep mmu enabled when requested iommu/omap: Remove redundant clock handling on ISR iommu/amd: Remove obsolete comment iommu/amd: Don't use 512GB pages iommu/tegra: smmu: Move bus_set_iommu after probe for multi arch iommu/tegra: gart: Move bus_set_iommu after probe for multi arch iommu/tegra: smmu: Remove unnecessary PTC/TLB flush all tile: dma_debug: add debug_dma_mapping_error support sh: dma_debug: add debug_dma_mapping_error support powerpc: dma_debug: add debug_dma_mapping_error support mips: dma_debug: add debug_dma_mapping_error support microblaze: dma-mapping: support debug_dma_mapping_error ia64: dma_debug: add debug_dma_mapping_error support c6x: dma_debug: add debug_dma_mapping_error support ARM64: dma_debug: add debug_dma_mapping_error support intel-iommu: Prevent devices with RMRRs from being placed into SI Domain ...

Enable COMMON_CLK in the Kconfig. 2. Remove private clock APIs, which are replaced by the code in drivers/clk/clk-ls1x.c. 3. Modify header file for drivers/clk/clk-ls1x.c.

| | * | | | | | MIPS: Netlogic: Support for XLR/XLS Fast Message NetworkGanesan Ramalingam2012-11-0912-12/+1020

The FMN queues and credits needs to be configured and intialized before it can be used. The co-processor 2 on XLR/XLS CPU cores has registers for FMN access, and the XLR/XLS has custom instructions for sending and loading messages. The FMN can deliver also per-cpu interrupts when messages are available at the CPU. This patch adds FMN initialization, adds interrupt setup and handling, and also provides support for sending and receiving FMN messages.

This simplifies IRQ handling for multi-SoC as well as the single SoC cases. Also split the setup of percpu and PIC interrupts so that we can configure the PIC interrupts for every node.
