[PATCH v3 0/3] usb: musb: cppi41: Add a way to manage DMA irq

[Alexandre Bailon <abailon-rdvid1DuHRBWk0Htik3J/w@public.gmane.org>]

This series was "dmaengine: cppi41: Make the driver more generic".
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
