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)

Please run https://github.com/lznuaa/dt-format for new dts to keep nice
node order,
If output result is not good enough, let know

Hi Frank,
It has much more commonality with the gw7903 - I'll submit a v2 using
that as a base.

I notice you asking people to do this but is that tool robust? Every
dts I through at it crashes:
$ git clone https://github.com/lznuaa/dt-format.git
$ cd dt-format
$ make
$ ./dt-format ~/linux-6.18/arch/arm64/boot/dts/freescale/imx8mm-evk.dts

Every version I've tried crashes. It crashes for me on v6.18 of
arch/arm64/boot/dts/freescale/imx8mm-evk.dts. See
https://github.com/lznuaa/dt-format/issues/4 - reverting the latest
patch resolves the issue.
Is using dt-format really a requirement? If this is a requirement it
should probably be picked up and integrated into the dtc somehow or at
least properly maintained? There are issues reported that appear very
valid to me that have not been addressed in 7 months time among them
being the fact it crashes on most dts and some of the ordering rules
that have not been the norm:
https://github.com/lznuaa/dt-format/issues
I welcome a tool that helps streamline the dts process but this tool
appears to need some work.

Thanks, let me debug it.

Sorry, I missed it. I will monitor this project closely.

Yes, let me fix this issue firstly.
