Do you have any CRU errors in the boot log? Can you check for the presence of clk_ref_usb3otg in /sys/kernel/debug/clk/clk_summary?quoted
cru errors in dmesg - seems no any. here is my dmesg: https://gist.github.com/warpme/ecf38482cc88fb68471355d011ecf974 For clk_ref_usb3otg i’m getting following: root@myth-frontend-e67a8de4c815:~ # cat /sys/kernel/debug/clk/clk_summary | grep usb3 clk_usb3otg_suspend 0 0 0 30770 0 0 50000 N deviceless no_connection_id clk_usb3otg_ref 0 0 0 24000000 0 0 50000 N deviceless no_connection_id clk_ref_usb3otg 0 0 0 24000000 0 0 50000 Y deviceless no_connection_id pclk_usb3_grf 0 0 0 75000000 0 0 50000 Y deviceless no_connection_id pclk_usb3phy_pipe 0 0 0 75000000 0 0 50000 N deviceless no_connection_id pclk_usb3phy_otg 0 0 0 75000000 0 0 50000 N deviceless no_connection_id clk_ref_usb3otg_src 0 0 0 37500000 0 0 50000 N deviceless no_connection_id aclk_usb3otg 0 0 0 150000000 0 0 50000 N deviceless no_connection_id
I'm at a loss here, I applied the patches to a clean 6.9 tree and even built it as a module (thank you for the sentinel). I have no issues. I'm wondering if it's your .config or something about your bootloader.
