[PATCH v4 0/5] Qualcomm DWC3 USB support

[Caleb Connolly]

This series enables support for Qualcomm platforms in the DWC3 driver,
adds support for arbitrary sector sizes to the USB mass storage gadget,
and fixes an issue with the CDC ACM driver where it wouldn't initialise
the USB device.

Additionally, it fixes a syntax bug in the Qualcomm SMMU driver, and
makes USB_DWC3_GADGET select DM_USB_GADGET to fix compilation with
gadget mode.

This is part of a larger series enabling DWC3 USB support on Qualcomm
platforms, a feature branch with all patches can be found at [1].
