Currently, the driver maps the USBSS's registers and uses it to enable / disable / clear the interrupt. That's not anormal because the CPPI 4.1 DMA is highly tied to USB but it make more difficult to add support of a new platform. This series update MUSB driver and platform driver to make CPPI 4.1 driver more generic. Note that I only have tested roughly the series. I'm planning to it more when I will have finished to rebase the series "dmaengine: cppi41: Add dma support to da8xx" on top of this one.
