I should have changed the title of the series to "Fix the DWC3 generic driver" In the current release all the platforms relying on the dwc3-generic driver are broken because of the usage of MISC uclass. This series among other things fixes it.

Are you able to somehow reduce this to a smaller fix for current release ? I see I have this series applied for -next now.

For the uclass fix, only the following patches are required: dm: Add a No-op uclass usb: dwc3: Use UCLASS_NOP instead of UCLASS_MISC for the DWC3 generic glue I've just tested with only those 2 patches on a DRA7-evm The rest are improvements and fixes specific to the K2 platforms JJ > > I see I have this series applied for -next now. >

Well, if you have some fixes (and only fixes, not 18-patch large series which reworks stuff) for current release, please send them. Otherwise, rebase on usb/next and send that too. However, please mark the patches somehow, so I know where they are supposed to go (next or master).

The mode selection for the DWC3 is kind of obsolete. The driver does not have to be host only or gadget only. This choice is confusing. All the remaining callers of dwc3_uboot_init() explicitly set dr_mode before calling the function, so none rely on a default behavior. Remove the choice menu and keep only the USB_DWC3_GADGET option. Enable it by default if USB_GADGET and USB_DWC3 are enabled. It must be disabled for the evb-rk3328 as it uses DWC2 for the gadget and DWC3 for the host.
