-Subject: [PATCH] overlays: dwc2: Increase RX FIFO size
-
-The previous version of the dwc2 overlay set the RX FIFO size to
-256 4-byte words. This sounds large enough for a 1024 byte packet (the
-largest isochronous high speed packet allowed), but it doesn't take
-into account some extra space needed by the hardware.
-
-Minas Harutyunyan at Synopsys (the source of the DWC OTG design)
-came up with a more correct value, 301, but since there is spare packet
-RAM this can be increased to 558 to allow two packets per frame.
