[PATCH v2] ARM: dts: imx: Add GW5913 board support

From: Robert Jones
Date: Thu Dec 12 2019 - 14:58:47 EST


The Gateworks GW5913 is an IMX6 SoC based single board computer with:
- IMX6Q or IMX6DL
- 32bit DDR3 DRAM
- FEC GbE RJ45 front-panel
- 1x miniPCIe socket with PCI Gen2, USB2
- 1x miniPCIe socket with PCI Gen2, USB2, nanoSIM
- 6V to 60V DC input connector
- GPS (ublox ZOE-M8Q)
- bi-color front-panel LED
- 256MB NAND boot device
- nanoSIM socket
- user pushbutton
- Gateworks System Controller (hwmon, pushbutton controller, EEPROM)

Changes in v2:
- Generalized node names
- Removed unnecessary labels
- Expanded patch subject
- Removed undocumented compatible string in dts**

** I realize that the "gw,ventana" still exists here, but that cant be removed
without breaking a conditional check in arch/arm/mach-imx/mach-imx6q.c
