+Subject: [PATCH 2/2] usb: dwc2:  add support for other Lantiq SoCs
+
+The size of the internal RAM of the DesignWare USB controller changed
+between the different Lantiq SoCs. We have the following sizes:
+
+Amazon + Danube: 8 KByte
+Amazon SE + arx100: 2 KByte
+xrx200 + xrx300: 2.5 KByte
+
+For Danube SoC we do not provide the params and let the driver decide
+to use sane defaults, for the Amazon SE and arx100 we use small fifos
+and for the xrx200 and xrx300 SCs a little bit bigger periodic fifo.
+The auto detection of max_transfer_size and max_packet_count should
+work, so remove it.
