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 v2:
- Fix some typo in commit messages
- Add more explanation about some changes made by patch 2 in commit message

Alexandre Bailon (2):
  usb: musb: cppi41: Add new methods for platform driver
  usb: musb: cppi41: Detect aborted transfers in cppi41_dma_callback()
