[PATCH 2/2] arm64: dts: freescale: Add imx8mp-venice-gw71xx-2x

From: Tim Harvey
Date: Wed Jun 07 2023 - 13:07:46 EST

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
