    80  1. The Newport product family uses the MCP25625 CAN over SPI device thus the spi--thunderx (SPI_THUNDERX) driver is required in addition to the mcp251x (CAN_MCP251X) driver. Also, note the Thunderx SPI controller only supports half-duplex transactions requiring a patch to the mcp251x driver to make it operating as half-duplex: [https://github.com/Gateworks/linux-newport/commit/f284504b771b8741222ac54fd2d773d88e53de39 can: mcp251x: convert driver to half-duplex SPI]
    81  2. The GW551x does not have a transceiver on board; CAN_RXD / CAN_TXD go to application connector

    8273 3. A Mini-PCIe expansion card may be used. See the [#minipcie Mini-PCIe] section at the end of this wiki page.
    8374 4. On newer kernels this is configured via device-tree and thus manual gpio manipulation (described below) is not necessary
