The following patch series adds USB 2.0 support for the Wii PowerPC platform via the EHCI controller present in the "Hollywood" chipset of the video game console. The first iterations (v1 to v3) of this patchset were submitted as RFC PATCH. The patchset is now sent as PATCH targetted for mainline inclusion. v3 -> v4 - Set the default IO TLB size via io_tlb_nslabs. Suggestion by Konrad Rzeszutek Wilk. - Use kernel command line instead of device tree to tell the kernel about the location and size of the mem2_dma region. Suggestion by Segher Boessenkool. - Keeps using v4 of the USB HCD_NO_COHERENT_MEM patch Albert Herranz (11): powerpc: add per-device dma coherent support powerpc: add min_direct_dma_addr swiotbl: add back swiotlb_alloc_boot() swiotlb: support NOT_COHERENT_CACHE PowerPC platforms swiotlb: add swiotlb_set_default_size() USB: refactor unmap_urb_for_dma/map_urb_for_dma USB: add HCD_NO_COHERENT_MEM host controller driver flag wii: have generic dma coherent wii: add mem2 dma mapping ops wii: enable swiotlb wii: hollywood ehci controller support arch/ia64/include/asm/swiotlb.h | 10 + arch/powerpc/boot/wii.c | 44 +++++ arch/powerpc/include/asm/device.h | 1 + arch/powerpc/include/asm/dma-mapping.h | 3 + arch/powerpc/include/asm/swiotlb.h | 3 + arch/powerpc/include/asm/wii.h | 25 +++ arch/powerpc/kernel/dma.c | 5 + arch/powerpc/platforms/embedded6xx/Kconfig | 3 + arch/powerpc/platforms/embedded6xx/Makefile | 2 +- arch/powerpc/platforms/embedded6xx/wii-dma.c | 265 ++++++++++++++++++++++++++ arch/powerpc/platforms/embedded6xx/wii.c | 2 + arch/x86/include/asm/swiotlb.h | 10 + drivers/usb/core/buffer.c | 29 +++- drivers/usb/core/hcd.c | 233 ++++++++++++++++------- drivers/usb/core/hcd.h | 13 +- drivers/usb/host/Kconfig | 8 + drivers/usb/host/ehci-hcd.c | 5 + drivers/usb/host/ehci-hlwd.c | 233 ++++++++++++++++++++++ drivers/usb/host/ehci.h | 23 +++ include/linux/swiotlb.h | 4 + include/linux/usb.h | 5 + lib/swiotlb.c | 60 +++++- 22 files changed, 892 insertions(+), 94 deletions(-) create mode 100644 arch/powerpc/include/asm/wii.h create mode 100755 arch/powerpc/platforms/embedded6xx/wii-dma.c create mode 100644 drivers/usb/host/ehci-hlwd.c -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
