there are (at least) 4 models/revisions in Tronsmart Orion R68, Meta
or Pro, 100M or 1000M ethernet. probably there are more variants from
other vendors based on same board.
I don't say all variants need to be supported here now, but it may
need few more description.

I have Orion R68 Meta 1000M version. there is a label on the board,
"Netxeon RK68G V2.0 2G/16G/AP6335". it might be called
"netxeon,rk68g-v2.0" or something like that.

on my board, there is no "purple" LED, <&gpio3 29 GPIO_ACTIVE_HIGH> is
red LED, <&gpio0 12 GPIO_ACTIVE_HIGH> is blue LED.

did you already confirm all GPIO connection written in your dts?

uart4 is working for me. (as a console)
