This series applies on top of u-boot-usb/master. It is available on github: https://github.com/jjhiblot/u-boot/tree/dm_usb_am335x_am437x_v2_rebased Travis report is available here: https://travis-ci.org/jjhiblot/u-boot/builds
The am433x platforms can use the generic DWC3 driver instead of relying on the dwc3-xhci driver. The am335x platforms use the musb controller. With a bit of work it can be made to support DM as well. This series only enables DM_USB and DM_USB_GADGET on am335x_boneblack_vboot. The changes for the other am335x based platforms will come in a subsequent series that reworks the configs of several TI boards.
This is part of a work to move all TI's platforms to support DM_USB and DM_USB_DEV. As a side effect it makes it easy to support the full USB RDNIS bootflow (bootrom loads SPL over RNDIS, SPL loads u-boot over RNDIS, u-boot loads the images over RNDIS)
This series is made of 2 parts: - am437x support for DM_USB and DM_USB_GADGET - am335x support for DM_USB and DM_USB_GADGET
Tested on: - am4372 evm - beaglebone black - am335x evm (to verify that it doesn't break anything)
Changes in v2: - use CONFIG_IS_ENABLED(DM_USB_GADGET) instead of CONFIG_DM_USB_GADGET - use CONFIG_SPL_DM_USB and CONFIG_SPL_DM_USB_GADGET - don't fail to bind "ti-musb-wrapper" if it is not possible to bind either the host or the gadget driver. - simplify #ifdef trickery thanks to the new SPL_DM_USB option
