Subject: [PATCHv1 0/3] Meson-8b and Meson-gxbb Fix some missing code
Date: Tue, 13 Jul 2021 05:52:12 +0000 [thread overview]
Message-ID: <20210713055227.1142-1-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 hot plug 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.

Dopped the reoder of code changes as of now.
Thanks
