[PATCH v3 00/15] usb: dwc3: Add new updates for DWC_usb31

[Thinh Nguyen]

This patch series adds new updates and some fixes for DWC_usb31.

Changes in v3:
 - Add "usb: dwc3: Check controller type before setting speed" to series

Changes in v2:
 - Add another patch to the series to increase mass_storage max_speed
 - Separate "usb: dwc3: ep0: Reset TRB counter for ep0 IN" from series
 - Separate "usb: dwc3: gadget: Set maxpacket size for ep0 IN" from series
 - Use msleep() instead of mdelay() for SoftReset PHY sync delay
 - Rename new USB31 macros from DWC3_USB31_* to DWC31_*
 - Rename device properties and replace '_' with '-'
 - Minor fixes in the commit messages

[PATCH v3 08/15] usb: dwc3: Make TX/RX threshold configurable

[Thinh Nguyen]

DWC_usb31 periodic transfer at 48K+ bytes per interval may need
modification to the TX/RX packet threshold to achieve optimal result.
Add properties to make it configurable.

[PATCH v3 12/15] usb: dwc3: Add disabling of start_transfer failure quirk

[Thinh Nguyen]

In DWC_usb31 version 1.70a-ea06 and prior needs a SW workaround for isoc
START TRANSFER command failure. However, some affected versions may have
RTL patches to fix this without a SW workaround. Add this quirk to
disable the SW workaround when it is not needed.

endpoints.

What are the defaults if not set?

By default, periodic ESS TX and RX threshold are not enabled. To enable 
TX or RX threshold, both packet threshold count and max burst size must 
be set to a non-zero value.

Unfortunately, I did not document it in this file after I made a change 
to remove the enabling of TX/RX threshold property. I can update this 
patch series with this information. Thanks.

BR,
Thinh
