So I'll add:
+&vcc_5v {
+       gpio = <&gpio GPIOH_8 GPIO_OPEN_DRAIN>;
+       enable-active-high;
+};

in odroid.dtsi instead in this patch.
that sounds good to me

Not sure what to do about the regulator-hub_5v.
maybe dropping this regulator overall? we're using gpio-hogs elsewhere
for the USB hub's reset line
or dropping the gpio-hog and keeping this regulator to manage GPIOH_4
I'll drop it completely, it makes no sense to have a regulator for a HUB reset anyway.

Neil

Best regards,
Martin
