So it shall be audio_ext: oscillator-audio { ...

Ok - enet_ext: oscillator-ethernet { ...

The dspi IP block provides SPI communication with variety of devices
(connected via external cable).

>>From SW point of view, the spidev driver is used. User space program(s)
via the /dev/spidevX.Y device communicate with connected HW.

I would need "just" to add:
+       { .compatible = "fsl,vf610-dspi" },

in drivers/spi/spidev.c

I'm wondering what is the actual policy - such "adjustments" are in the
end very board specific.

I'm not sure - last time I've submitted DTS for imx6q board the
maintainer required to make it _all_ alphabetically sorted.

(I haven't heard about the rule to put some node to the end of file
because of its size).

Yes, they are used by user space programs.

Yes, I'm aware of that.
