This patch set addresses this issue and also adds XHCI-compliant USB Controller ACPI identification into xhci-platform driver. Changes from v7: - Only use dma_coerce_mask_and_coherent when dma_mask is NULL - Check the controller DMA capability and configure 32-bit dma_mask if it only supports 32-bit DMA - Patches is generated over v4.3-rc1 Changes from v6: -Add WARN_ON if dma_mask is NULL -Use dma_coerce_mask_and_coherent to assign dma_mask and coherent_dma_mask Change from v5: -Change comment to "XHCI-compliant USB Controller" as "PNP0D10" ID is not X-Gene specific -Change comment -Assign dma_mask to coherent_dma_mask if dma_mask is NULL to make sure dma_set_mask_and_coherent does not fail prematurely. Changes from v4: -Remove #ifdef CONFIG_ACPI -Change comment -Assign dma_mask to coherent_dma_mask if dma_mask is NULL to make sure dma_set_mask_and_coherent does not fail prematurely. Changes from v3: -Regenerate the patch over 4.2-rc5 -No code change Changes from v2 -Replaced tristate with a boolean as the driver doesn't compile as a module -Correct --help-- to ---help--- Changes from v1 -Consolidated to use dma_set_mask_and_coherent -Got rid of the check against sizeof(dma_addr_t) -Renamed from "add support for APM X-Gene to xhci-platform" -Removed changes to arm64/Kconfig -Made CONFIG_USB_XHCI_PLATFORM a user selectable config option drivers/usb/host/xhci-plat.c | 29 ++++++++++++++++++++++------- drivers/usb/host/xhci.c | 10 ++++++++++ 2 files changed, 32 insertions(+), 7 deletions(-) -- 1.9.1
