Hi Marek

Thank you for the patch

Not all parts, but for my related part only

Tested-by: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

One concern from my side is

> +		/* No FAN connected by default. */
> +		status = "disabled";
> +	};

Indeed "base kit" doesn't have FAN, but "complete kit" will have, and
official page/site will recommend to buy and use it because the board will
be very hot. Default "enable" is better idea, IMO.
But it is not a big deal for now. Additional patch instead of v2 is OK for me.

Thank you for your help !!
