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

[Alexandre Bailon <abailon-rdvid1DuHRBWk0Htik3J/w@public.gmane.org>]

This series adds support of da8xx to cppi41 dma controller driver.
This update the cppi41 driver to make it more generic (was only supporting
the am335x), and implement the support for the da8xx.
Some other changes are required in platform and musb drivers to make the dma
work on da8xx (though, it should build correctly and should not cause
any issues).

The changes have been tested on the beaglebone black and omapl138-lcd.
I haven't noticed any regression on beaglebone black
(though I have noticed some performence issues since 4.9).

On on da8xx, I have sometime some warnings happening during a teardown.
I only got them while I was running some corner cases and I'm still trying
to fix them. 
Anyway, this warnings doesn't seem to cause any issues as usb keep working
after they happen.

I also got some issues related to pm runtime.
I tried to fix them with the series "dmaengine: cppi41: PM runtime fixes",
but I still get few warnings sometime (again, doesn't seem to cause any issue).
