Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

The Gateworks Venice GW71xx-0x/GW72xx-0x/GW73xx-0x are development
kits comprised 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-controll, 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-controll, 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

v2:
- fix i.MX 8M Mini name in commit log
- consistent use of underscore vs hyphen in labels
- fix gsc interrupt type
- fix iomux group node names
- fix led-controller bindings:
(use correct node names, color, function and remove label)
- use accelerometer node name vs accel
- remove sai3 from gw71xx baseboard
- added serial connector description to commit message
- added I/O connector description to commit message
- removed unnecessary #address-cells/#size-cells from gpio-keys node
