[PATCH] usb: chipidea: Configure DMA properties and ops from DT

On certain platforms (e.g. ARM64) the dma_ops needs to be explicitly set to be able to do DMA allocations, so use the of_dma_configure() helper to populate the dma properties and assign an appropriate dma_ops. Signed-off-by: Bjorn Andersson ---

RE: USB oops regression caused by -stable patch

Thanks for reporting, Tony. It was remiss of me. There is another BOS free operation in label re_enumerate. This cause a double-free of BOS. USB2 doesn't have BOS desc, so you cannot reproduce it. I am on a travel. It is appreciated if you can help try below fix. Hi, Greg, I will commit a final

[PATCH 3/3] usb: musb: sunxi: support module autoloading

From: Emilio López MODULE_DEVICE_TABLE() is missing, so the module isn't auto-loading on sunxi systems using the OTG controller. This commit adds the missing line so it loads automatically when building it as a module and running on a system with an USB OTG port.

[PATCH 2/3] dmaengine: sun4i: support module autoloading

From: Emilio López MODULE_DEVICE_TABLE() is missing, so the module isn't auto-loading on supported systems. This commit adds the missing line so it loads automatically when building it as a module and running on a system with the early sunxi DMA engine.

[PATCH 1/3] [media] rc: sunxi-cir: support module autoloading

From: Emilio López MODULE_DEVICE_TABLE() is missing, so the module isn't auto-loading on systems supporting infrared. This commit adds the missing line so it works out of the box when built as a module and running on a sunxi system with an infrared receiver.
