"^gw,.*":

use "gateworks" vendor prefix
deprecated: true

;)

I'd be more interested in whether that -0x is a wildcard!

Are you sure you are using correct prefix? Anyway, keep alphabetical
order, so before "gw".

- LPDDR4 memory
- eMMC Boot device
- Gateworks System Controller (GSC) with integrated EEPROM, button
controller, and ADC's
- PMIC
- SOM connector providing:
- FEC GbE MII
- 1x SPI
- 2x I2C
- 4x UART
- 2x USB 2.0
- 1x PCI
- 1x SDIO (4-bit 3.3V)
- 1x SDIO (4-bit 3.3V/1.8V)
- GPIO

The GW7905 Baseboard contains the following:
- GPS
- microSD
- off-board I/O connector with I2C, SPI, GPIO
- EERPOM
- PCIe clock generator
- 1x full-length miniPCIe socket with PCI/USB3 (via mux) and USB2.0
- 1x half-length miniPCIe socket with USB2.0 and USB3.0
- USB 3.0 HUB
- USB Type-C with USB PD Sink capability and peripheral support
- USB Type-C with USB 3.0 host support

The 0x has to do with our part numbering scheme. The gw7905 is the
baseboard and the 0x is the SOM and we have SOM's with part loading
options that do not affect device-tree as reserved for 00 to 09.

I'll fix the sorting for v2.

Thanks,

Tim
