I have tried to separate as munch I could CPPI 4.1 MUSB driver changes. Currently, the DMA interrupt is managed by the CPPI 4.1 driver. The issue here is the CPPI 4.1 driver must access to MUSB glue registers to manage its interrupt. In order to move the interrupts management from CPPI 4.1 driver to MUSB (and then make it more generic), update the MUSB CPPI 4.1 driver with changes that will help to manage DMA interrupt from MUSB driver. Changes in v3: - Move a patch from another series to this one to avoid build error report from kbuild test robot - Instead of adding and exporting function, add one callback and a pointer to musb in struct dma_controller - Surround the DMA function introduced in musb_dsps with #ifdef / #endif. Changes in v2: - Fix some typo in commit messages - Add more explanation about some changes made by patch 2 in commit message Alexandre Bailon (3): usb: musb: dma: Add a DMA completion platform callback usb: musb: cppi41: Detect aborted transfers in cppi41_dma_callback() usb: musb: dsps: Manage CPPI 4.1 DMA interrupt in dsps drivers/dma/cppi41.c | 28 ++++------------ drivers/usb/musb/musb_cppi41.c | 20 ++++++++---- drivers/usb/musb/musb_dma.h | 4 +++ drivers/usb/musb/musb_dsps.c | 72 ++++++++++++++++++++++++++++++++++++++++-- 4 files changed, 95 insertions(+), 29 deletions(-) -- 2.10.2 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
