[PATCH 0/6] usb: dwc2: gadget: Fix TX FIFO handling

[John Youn]

Hi,

This is a resend of a patch series originally submitted by Robert
Baldyga back in February.

Somehow I missed it back then. Sorry about that.

It should fix some FIFO programming related issues on RPi and maybe
other platforms.

Also, this series makes the g-tx-fifo-size DT property obsolete. I've
added a patch at the end of the series to document that.

Regards,
John

[PATCH 6/6] Documentation: devicetree: dwc2: Deprecate g-tx-fifo-size

[John Youn]

This property is not needed because the periodic fifos are not
configurable. So it was incorrect to add this property in the first
place.
