I have already sent them countless times and even stuck CPPI 4.1 support (in arch/arm/common/cppi41.c) in Russell's patch system.

Inventra is a dedicated device's private DMA controller, why make universal DMA driver for it? > Once that's done, we drop MUSB's private API. Don't think it's a good idea.
