This patch series enables musb driver to adopt driver model. This has been tested on the following evms (logs [1]) by loading kernel and dtb from sata hard-disk. * AM335x GP evm * AM335x BBB
Also pushed a branch for testing [2]
This patch series depends on the following patch series * usb common code for DT parsing [4] * usb ether gadget DM conversion [5]
Changes from initial version: * Separated out the usb gadget driver patches from earlier musb series [3] for testing and submitting of dwc3 dm musb patches. * passed an dummy dev pointer for non-DM case as well for reducing the number of #ifdefs in musb backend driver.
