This is more a general concern. You're introducing the rk1 as a dts file
but the from looking at the module-page and your patch description
this is "just" a SOM that most likely cannot run without some sort of carrier
board.

In the rockchip devicetree directory you can see a number of som boards
as som-dtsi + base-board forming a full product. Simply because the number
of usable peripherals will highly depend on what baseboard is used.

Thanks
Heiko
