Maybe I don't understand the question.
There is no 'fsl-udc' that needs to be loaded at all. The USB driver
for imx is the chipidea driver.
In the imx27.dtsi we have:
usbotg: usb@10024000 {
compatible = "fsl,imx27-usb";
reg = <0x10024000 0x200>;
interrupts = <56>;
clocks = <&clks IMX27_CLK_USB_IPG_GATE>;
fsl,usbmisc = <&usbmisc 0>;
status = "disabled";
};
usbh1: usb@10024200 {
compatible = "fsl,imx27-usb";
reg = <0x10024200 0x200>;
interrupts = <54>;
clocks = <&clks IMX27_CLK_USB_IPG_GATE>;
fsl,usbmisc = <&usbmisc 1>;
status = "disabled";
};
usbh2: usb@10024400 {
compatible = "fsl,imx27-usb";
reg = <0x10024400 0x200>;
interrupts = <55>;
clocks = <&clks IMX27_CLK_USB_IPG_GATE>;
fsl,usbmisc = <&usbmisc 2>;
status = "disabled";
};
So the "compatible = "fsl,imx27-usb";" is all we need there.
