Normally we have the “modem” as a child of the UART node. So that would work for one connection, but not sure how we’d describe a second UART connection.

I think on of the uart’s could be considered the main connection point. But not sure it maters. I’m guessing we need a few standard properties to represent phandles to devices on buses that would normally have the nodes as children. So i2c, spi, uart, etc.. - k
