arm64: dts: imx8mm: Add Gateworks i.MX 8M Mini Development Kits
The Gateworks Venice GW71xx-0x/GW72xx-0x/GW73xx-0x are development kits consisting of a GW700x SoM and a Baseboard. Future SoM's such as the GW701x will create additional combinations. The GW700x SoM contains: - i.MX 8M Mini SoC - LPDDR4 DRAM - eMMC FLASH - Gateworks System Controller (eeprom/pushbutton/reset/voltage-monitor) - GbE PHY connected to the i.MX 8M Mini FEC - Power Management IC The GW71xx Baseboard contains: - 1x MiniPCIe Socket with USB2.0, PCIe, and SIM - 1x RJ45 GbE (i.MX 8M Mini FEC) - I/O connector with 1x-SPI/1x-I2C/1x-UART/4x-GPIO signals - PCIe Clock generator - GPS and accelerometer - 1x USB 2.0 Front Panel connector - wide range power supply The GW72xx Baseboard contains: - 2x MiniPCIe Socket with USB2.0, PCIe, and SIM - 2x RJ45 GbE (i.MX 8M Mini FEC and LAN743x) - 1x MicroSD connector - 1x USB 2.0 Front Panel connector - 1x SPI connector - 1x Serial connector supporting 2x-UART or 1x-UART configured as 1 of: RS232 w/ flow-control, RS485, RS422 - PCIe Clock generator - GPS and accelerometer - Media Expansion connector (MIPI-CSI/MIPI-DSI/GPIO/I2S) - I/O connector with 2x-ADC,2x-GPIO,1x-UART,1x-I2C - wide range power supply The GW73xx Baseboard contains: - 3x MiniPCIe Socket with USB2.0, PCIe, and SIM - 2x RJ45 GbE (i.MX 8M Mini FEC and LAN743x) - 1x MicroSD connector - 1x USB 2.0 Front Panel connector - 1x SPI connector - 1x Serial connector supporting 2x-UART or 1x-UART configured as 1 of: RS232 w/ flow-control, RS485, RS422 - WiFi/BT - PCIe Clock generator - GPS and accelerometer - Media Expansion connector (MIPI-CSI/MIPI-DSI/GPIO/I2S) - I/O connector with 2x-ADC,2x-GPIO,1x-UART,1x-I2C - wide range power supply Signed-off-by: Tim Harvey <tharvey@gateworks.com> Reviewed-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
