It's > obvious from the compatible it's a i.MX8MM board from Gateworks. 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

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
