That was because using it was breaking stuff, but now that we know better
which regulators are used for what, and which one we most add an always-on;
property too, I would greatly prefer you to acually use axp209.dtsi, see
e.g. the sun5i-a13-utoo-p66.dts file where I'm using it.

Can you please respin this patch using axp209.dtsi?

Also please do not add nodes for unused regulators, like the ldo-s for the csi-s.

Thanks & Regards,

Hans
