  The Gateworks imx8mp-venice-gw71xx-2x consists of a SOM + baseboard.

The GW702x SOM contains the following:
 - i.MX8M Plus SoC
 - LPDDR4 memory
 - eMMC Boot device
 - Gateworks System Controller (GSC) with integrated EEPROM, button
   controller, and ADC's
 - PMIC
 - SOM connector providing:
  - eQoS GbE MII
  - 1x SPI
  - 2x I2C
  - 4x UART
  - 2x USB 3.0
  - 1x PCI
  - 1x SDIO (4-bit 3.3V)
  - 1x SDIO (4-bit 3.3V/1.8V)
  - GPIO

The GW71xx Baseboard contains the following:
 - GPS
 - RJ45 GbE (eQoS)
 - off-board I/O connector with UART, I2C, SPI, GPIO
 - EERPOM
 - PCIe clock generator
 - full-length miniPCIe socket with PCI/USB3 (via mux) and USB2.0
 - USB Type-C with USB 2.0 host and peripheral support
 - Wide range DC input supply

Hi Shawn,

My notes say that pinctrl should come first (if needed) followed by
compatible, reg, other props, and finally status (if needed). Assuming
I'm wrong about that where in the list should pinctrl be and is this
documented anywhere for future reference?

Best regards,

Tim
