Add support for Texas Instuments Communication Port Programming Interface 4.1 (CPPI 4.1) used on OMAP-L137/DA830.
At this moment, only the DMA controller and queue manager are supported. Support for the buffer manager is lacking but this chip doesn't have it anyway.
Is this usable for anything other than the musb_hdrc driver?
On DA830? No.
ISTR the Ethernet controller uses some flavor of CPPI too.
It's CPPI 3.0.
But CPPI wasn't "broken by design" in that context, like it was for USB RX, so they may not have changed it there.
They have Ethernet using CPPI 4.1 but on Puma 5.
If this is only for the MUSB driver, it might be better to stash this code in driver/usb/musb and generalize the current CPPI glue there.
Generalize what? There's no way CPPI 3.0 and 4.1 can be "generalized", they're too unlike.
