Subject: [PATCHv2 0/4] Meson-8b and Meson-gxbb Fix some missing code
Date: Fri, 16 Jul 2021 10:36:32 +0000	[thread overview]
Message-ID: <20210716103651.1455-1-linux.amoon@gmail.com> (raw)

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

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@gmail.com/
Dopped the reoder of code changes as of now.

V1 > changes Fixed the GPIO input signal on Odroid C1+/C2
     New patch added to fix Odroid C2.

Thanks
-Anand
