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.
|
||
