The GW7904 is based on the i.MX 8M Mini SoC featuring:
- LPDDR4 DRAM
- eMMC FLASH
- microSD connector with UHS support
- LIS2DE12 3-axis accelerometer
- Gateworks System Controller
- IMX8M FEC
- 2x RS232 off-board connectors
- PMIC
- 10x bi-color LED's
- 1x miniPCIe socket with PCIe and USB2.0
- 802.3at Class 4 PoE
- 10-30VDC input via barrel-jack

But isn't it clear that you need to go to the device-tree itself to
understand the details?
As far as basic features go sometimes there is very little difference
in these board models. It would be a struggle to list all the board
details (which I do in the dts commit) in a way that doesn't take up
too much space in fsl.yaml.
Best Regards,
Tim

But then the comment you added is useless. So either add useful comment
or no comment. :)

Krzysztof,
so are you saying that no comment is fine here as well? It seems to me
that most of the comments in that file look just like mine which I
agree are about just as descriptive as the compatible string.
For discussion purposes here is for example the commit log for the GW7904 dts:
The GW7904 is based on the i.MX 8M Mini SoC featuring:
- LPDDR4 DRAM
- eMMC FLASH
- microSD connector with UHS support
- LIS2DE12 3-axis accelerometer
- Gateworks System Controller
- IMX8M FEC
- 2x RS232 off-board connectors
- PMIC
- 10x bi-color LED's
- 1x miniPCIe socket with PCIe and USB2.0
- 802.3at Class 4 PoE
- 10-30VDC input via barrel-jack
And the comit log for the very similar GW7903 dts:
The GW7903 is based on the i.MX 8M 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
- 2x 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)
Best Regards,
Tim

The binding doesn't seem to define the number explicitly. I understand
we use hex in unit-address, but not sure a hex number is better than
decimal as part of node name, mostly meant to count the instance.
