-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.
