The GW7906 is based on the i.MX8M Mini SoC featuring:
- LPDDR4 DRAM
- eMMC FLASH
- microSD connector with UHS support
- LIS2DE12 3-axis accelerometer
- Gateworks System Controller
- IMX8M FEC
- software selectable RS232/RS485/RS422 serial transceiver
- PMIC
- 1x isolated RS232 UART
- 1x off-board bi-directional opto-isolated digital I/O
- 1x M.2 A-E Key Socket and 1x MiniPCIe socket with USB2.0 and PCIe
(resistor loading to route PCIe/USB2 between M.2 and MiniPCIe socket)
The GW7906 has much in common with the GW7903 so it is used as a base.
Differences include:
- different GbE PHY
- a couple of new GPIO's added
- removal of uart1
- removal of io-expander
Signed-off-by: Tim Harvey <tharvey@gateworks.com>
---
v2:
- ran through dt-format
- use gw7903 as a base due to little difference in boards

In
https://lore.kernel.org/imx/20260123-gifted-wolverine-from-mars-47b9d4@quoll/
don't prefer dts include dts.
Can you create common dtsi?
then both mx8mm-venice-gw7906.dts and mx8mm-venice-gw7903.dts include
this common dtsi.
Ref the method at
