ON BOARD PERIPHERALS
The Avnet SmartEdge IIoT Gateway has several onboard peripherals that a standard Pi does not. Many of these
peripherals connect to the SPI2 bus on the higher GPIOs, freeing up the GPIOs on the HAT for usage.
Some of these peripherals use a customized driver:
GPIO expansion: gpio_fxl6408
UART: sc16is7xx
CAN: mcp251x
Cellular: option, usb_wwan, qcserial, qmi_wwan
These driver changes are available from our github repo for the kernel (see section 4.1)
