Hi Hans,
with these regulators USB works on the Orange Pi Plus too.
I don't know if adding the regulators in the dts is okay, since most
regulators are defined in the sunxi-common-regulators.dtsi, but
we use different pins.
Thanks, I've added this to my sunxi-wip branch for now.
Regards,
Hans
p.s.
Any progress on getting the "core" H3 kernel support upstream ?
Given Arnd's remarks about how we should not hard-code the
indices in the clk driver + the very KISS nature of the
change to 1 parent-clk per gate setup I still believe
that that one is best.
Maxime ? Chen-Yu ? It would be really good to be able to
move forward with this, how do you want to proceed ?
