Subject: [PATCHv3 0/6] Meson-8b and Meson-gxbb Fix some missing code
Date: Tue, 17 Aug 2021 09:45:34 +0530	[thread overview]
Message-ID: <20210817041548.1276-1-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
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@gmail.com/
Dopped the reorder of code changes as of now.

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

[1] https://lore.kernel.org/linux-devicetree/20210716103651.1455-1-linux.amoon@gmail.com/

V2 > changes Fixed the GPIO polarity for Odroid C1
     fix the power source from phy-supply to vbus-supply 
     added new patches to fix resolve some issues.

Thanks
-Anand
