You would prefer that the csi is broken on the lime then?  Unlike the cubieboards, 
ldo3 & ldo4 really are used on the olimex boards. So it seems that as yet you still 
don't know enough about which regulators are used, or you wouldn't be asking for 
that.

That's the major disadvantage of axp209.dtsi, the regulator node isn't describing 
the pmic at all. Instead it's describing the stuff connected to the pmic outputs, 
which is undeniably board specific and therefore totally unsuitable for a generic
file. Leading to every board needing to override everything regardless.

So no, I'm not going to respin the patch. I strongly believe using axp209.dtsi is 
the wrong thing to do here.
If that means the patch doesn't make it in, then so be it.

Rgds,
Iain
