"[PATCH 00/11] dmaengine: cppi41: Add dma support to da8xx"

This series intend to make the CPPI 4.1 more generic in order to
add a new platform (the DA8xx).
To achieve that, all the IRQ code present in CPPI 4.1 driver has been moved
to MUSB DSPS driver.
Other changes mainly update the glue layer and platform code to make the
whole driver more generic.

So does da8xx use CPPI 4.1 DMA for other devices also in addition to
musb?

   No. DA8xx CPPI 4.1 is implemented as a part of the MUSB peripheral.
But there were a SoC (support for which never got merged upstream) where CPPI
4.1 DMA is not limited to USB.

FWIW, the SoC was called TI Puma5, the support for it was filed by TI into arch/arm/mach-avalanche/...
