Doing a git bisect between v4.2..v4.3-rc1 on it pointed to: ddef08dd00f5 ("Driver core: wakeup the parent device before trying probe") With the commit above reverted things work fine with DMA and USB gadgets. This is on omap3 with CONFIG_USB_INVENTRA_DMA selected. Selecting CONFIG_MUSB_PIO_ONLY still works even without reverting ddef08dd00f5. Anybody got ideas what might be wrong? Some wrong runtime PM usage under drivers/usb/musb?
