Chip Idea host usb hub port power switching

Hi, I was trying to get the USB Hub Port Power Switching to work, when I came across an - apparently - odd behavior: If CI_HDRC_TURN_VBUS_EARLY_ON is enabled[0], the regulator (reg_vbus) is not remembered and thus not switchable by the ehci_ci_portpower routine[1] later on. Is this behavior inte
