[PATCH v2 2/2] arm64: dts: freescale: Add imx8mp-venice-gw72xx-2x

From: Tim Harvey
Date: Wed Jul 19 2023 - 12:15:43 EST

The Gateworks imx8mp-venice-gw72xx-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 GW72xx Baseboard contains the following:
- GPS
- microSD
- off-board I/O connector with SPI
- off-board I/O connector with I2C, and GPIO
- off-board I/O connector with MIPI DSI, MIPI CSI, I2C, and GPIO
- off-board I/O connector with RS232 and RS485
- EERPOM
- USB 3.0 HUB
- USB 3.0 TypeA socket
- USB 2.0 Micro-B OTG socket
- Accelerometer
- 1x GbE (eQoS)
- 1x GbE (PCI)
- PCIe clock generator
- PCIe switch
- 1x full-length miniPCIe socket with PCI and USB2.0
- 1x full-length miniPCIe socket with PCI/USB3 (via mux) SIM, and USB2.0
- 1x half-length miniPCIe socket with USB2.0 and USB3.0
- USB Type-C with USB PD Sink capability and peripheral support
- USB Type-C with USB 3.0 host support
- Wide range DC input supply
