On Odroid C1+ and Odroid C2 USB feature is broken It's being observed the after initiation of USB phy the USB port goes in to suspend state, If we pass usbcore.autosuspend=-1 via command line USB hotplug seen to be working. Another issue I observed is increase of USB interrupts event even if there is not much activity on USB ports. $ cat /proc/interrupts | grep usb 35: 26462800 0 0 0 GIC-0 63 Level c90c0000.usb, dwc2_hsotg:usb1 8 Changes added power node to usb phy and small code cleanup in usb phy. Previous version RFC. [0] https://patchwork.kernel.org/project/linux-amlogic/cover/20210617194154.2397-1-linux.amoon@xxxxxxxxx/ Dopped the reorder of code changes as of now.
