Please drop "spidev item", because there is no such hardware as spidev.
It's Linuxism and its appearance in bindings only creates confusion for
further submissions (which are rejected...).

Please explain here the hardware, which in this context is the
connection between Arduino and Linux. You received comments that this is
not a trivial device, so please bring the hardware description which
will prove it is indeed a trivial device. Why don't you need supplies
for example?

Placeholders for spidev are not allowed, so you have entire commit msg
to convince us that you are doing something else.

I already asked for that so I won't be repeating again at v3.


Best regards,
Krzysztof

... plus some hardware details on that MCU, e.g. its processor or to
which SPI controller it is wired on the board.
