[PATCH v3 00/14] usb: dwc2: Add host and gadget driver

[Jules Maselbas]

This patchset add USB host and gadget support for the DWC2 controller
The host driver is ported from the U-Boot driver, some part are taken
taken from Linux.

The gadget driver is ported from Linux and only support direct dma (not
descriptor based) and does not support direct buffer although this could
be nice to have.

changes since v2:
 - rework timeout handling for networking
 - use usb_register_otg_device
 - rework gadget fifo allocation
 - modified makefile/kconfig for host or gadget only
