[PATCH 0/4] usb: musb: da8xx: Add DMA support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series update musb driver to add DMA support to da8xx.
To work correctly, the follwings patches are required:
"dmaengine: cppi41: Add dma support to da8xx",
"ARM: davinci: da850: Share the usb20 clock",
"ARM: dts: da850: Enable cppi41 dma",
"dmaengine: cppi41: PM runtime fixes"

I haven't changed yet the davinci_all_defconfig to enable the DMA mode
by default. I'm planning to do it once all the warnings happening during
the teardwon will be fixed.

The series has been tested on beaglebone black and omapl138-lcdk
in both host mode (pendrive, headset, wifi, webcam) and device mode
(MSC, CDC).
Expect few warnings on omapl138-lcdk, I haven't noticed any issues.
