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
v2:
* Remove the DMA 'enable' bindings and make them autodetected.
* Add DMA 'disable' bindings to override.
* Separate out commit to add '__packed' attribute.
* Don't print errors on -ENOMEM.
* Remove unnecessary GFP_ATOMIC flags.
* Remove unnecessary patch removing a WARN_ON.
* Reorganize and clarify BNA interrupt.
* Fix issue with enabling STSPHSERCVD interrupt.
Regards,
John
