I do think that each sequence should be contained within a single
property, but I'm open to other suggestions.

IIRC a very early prototype did implement something like that. However
because of the resource issues this had to be string based, so that the
sequences looked somewhat like (Alex, correct me if I'm wrong):

	power-on = <"REGULATOR", "power", 1, "GPIO", "enable", 1>;

Instead we could possibly have something like:

	power-on = <0 &reg 1,
		    1 &gpio 42 0 1>;

Yes, that would work, although I still think it would be a good idea to
split the used resources off into the gpios/pwms/regs/etc properties.

Where the first cell in each entry defines the type (0 = regulator, 1 =
GPIO) and the rest would be a regular OF specifier for the given type of
resource along with some defined parameter such as enable/disable,
voltage, delay in ms, ... I don't know if that sounds any better. It
looks sort of cryptic but it is more "in the spirit of" DT, right Grant?

It is still kind of a ham-handed approach, but it does fit better with
existing conventions than the hierarchy of nodes does.
