[PATCH 00/30] usb: dwc2: Gadget descriptor DMA and IOT

[John Youn <johnyoun-HKixBCOQz3hWk0Htik3J/w@public.gmane.org>]

This series implements gadget-side descriptor DMA for the DWC_hsotg
controller.

It also includes support for DWC USB IOT controllers which use the
descriptor DMA mode of operation exclusively. These are two new
device-only USB controller IPs based on DWC_hsotg.

Tested on HAPS platform with:
* HSOTG IP version 3.30a
* FS/LS IOT IP version 1.00a
* HS IOT IP version 1.00a

This series should be applied on top of:
