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 ® 1,
1 &gpio 42 0 1>;
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?
Writing this down, it seems to me like even that proposal was already
discussed at some point. Again, Alex may remember better.
