Should this be "wii"?

This can go I think, unless you plan on supporting something else  
than mini?

> +#ifdef CONFIG_STARLET_MINI

> +#define HW_RESETS_OF_COMPATIBLE	"nintendo,hollywood-resets"
> +#define HW_GPIO_ALIAS		"hw_gpio

This should be unconditional now I think?  You access the hardware  
directly.

Don't use an alias here, search for e.g. a matching "compatible"  
instead.

Like with Flipper, why a platform bus?

> +#ifdef CONFIG_STARLET_MINI
> +	{ .compatible = "twiizers,starlet-mini-ipc", },
> +#endif

This one should go completely, I will have more to say about it when  
I get
to review the device trees (saving those for last :-) ).
