MIPS: Replace setup_irq() by request_irq()

2020-03-05T15:47:35Z

request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq(). remove_irq() has been replaced by free_irq() as well. There were build error's during previous version, couple of which was reported by kbuild test robot of which one was reported by Thomas Bogendoerfer as well. There were a few more issues including build errors, those also have been fixed.

dma-mapping: drop the dev argument to arch_sync_dma_for_*

2019-11-20T19:31:38Z

These are pure cache maintainance routines, so drop the unused struct device argument. Signed-off-by: Christoph Hellwig Suggested-by: Daniel Vetter

dma-mapping: explicitly wire up ->mmap and ->get_sgtable

2019-09-04T09:13:18Z

While the default ->mmap and ->get_sgtable implementations work for the majority of our dma_map_ops impementations they are inherently safe for others that don't use the page allocator or CMA and/or use their own way of remapping not covered by the common code. So remove the defaults if these methods are not wired up, but instead wire up the default implementations for all safe instances.

mips/jazz: remove the mapping_error dma_map_ops method

2018-12-06T14:56:38Z

The Jazz iommu code already returns (~(dma_addr_t)0x0) on mapping failures, so we can switch over to returning DMA_MAPPING_ERROR and let the core dma-mapping code handle the rest. Signed-off-by: Christoph Hellwig Acked-by: Linus Torvalds

dma-mapping: consolidate the dma mmap implementations

2018-09-20T07:01:16Z

The only functional differences (modulo a few missing fixes in the arch code) is that architectures without coherent caches need a hook to convert a virtual or dma address into a pfn, given that we don't have the kernel linear mapping available for the otherwise easy virt_to_page call. As a side effect we can support mmap of the per-device coherent area even on architectures not providing the callback, and we make previous dangerous default methods dma_common_mmap actually save for non-coherent architectures by rejecting it without the right helper. In addition to that we need a hook so that some architectures can override the protection bits when mmaping a dma coherent allocations.

dma-mapping: merge direct and noncoherent ops

All the cache maintainance is already stubbed out when not enabled, but merging the two allows us to nicely handle the case where cache maintainance is required for some devices, but not others. Signed-off-by: Christoph Hellwig Acked-by: Paul Burton # MIPS parts
