A13-SOM 512 USB0 doesn't work with Bullseye img

[dantonielli]

Hello,

I'm trying to migrate a previously made project to the new Bullseye image. Burn the image to an SD and place it on a 512 mB A13-SOm board.

I managed to boot without problem, but the USB0 OTG is not working (it does not detect any device).

In the image I used previously (Whezzy with kernel 3.4.90+) I was able to make this USB work with the following configuration:

[usbc0]
      usb_used = 1
      usb_port_type = 1;                
      usb_detect_type = 0;
      usb_id_gpio = ;
      usb_det_vbus_gpio =;
      usb_drv_vbus_gpio = port:PG12<1><0><default><0>
      usb_host_init_state = 1;

I understand that the most recent version of Debian performs the configuration through the device tree.

From here I can get that the .dtb that the u-boot is raising is sun5i-a13-olinuxino.dtb, but I can't edit it so that the port works.

sun5i-a13-olinuxino.dts file:

usb@1c13000 {
                        compatible = "allwinner,sun4i-a10-musb";
                        reg = <0x1c13000 0x400>;
                        clocks = <0x02 0x17>;
                        interrupts = <0x26>;
                        interrupt-names = "mc";
                        phys = <0x0e 0x00>;
                        phy-names = "usb";

                        status = "okay";
                        phandle = <0x36>;
                };

                        #phy-cells = <0x01>;

                        usb1_vbus-supply = <0x11>;
                        phandle = <0x0e>;
                };

I try modifying dr_mode="otg" to dr_mode="host" but it didn't work, I can't find the rest of the parameters


What i am missing?
I would appreciate any help.
