    Hi all,

    I'm trying to support Udoo board in OpenELEC. For that we have common imx6 project based on 3.14.25+ kernel. And of course because of this I'm having problem running kernel on udoo. I copied device tree files from 3.10.9 and compilation went well. But system didn't boot because of clock binding in usb:
    Code:
    &usbh1 {
    	pinctrl-names = "default";
    	pinctrl-0 = <&pinctrl_udoo_usbh1>;
    	vbus-supply = <&reg_usb_h1_vbus>;
    	/* if I have clk enabled stops booting
    	clocks = <&clks 201>;
    	clock-names = "phy";
    	*/
    	status = "okay";
    };
    But if I remove this 2 lines system boots but still no USB visible. There are some other issues with ethernet also but first I would like to fix this usb issue. Any help would be highly appreciated. I should probably mentioned that I'm no expert in this area. Wonder why there is no better device tree support in newer kernels... I'm using same kernel config as for Cubox-i and TBS Matrix systems.

    So i got this fixed. Seems my kernel missed a patch chipidea: ci_hdrc_imx: Allow handling the clock for an USB phy/hub.

    Now I think I have everything sorted out. OpenELEC support is very near.

    Ooh, I was just typing a message to motivate the udoo dev team to help you but saw your message while I switched to full editor.
    Thank you vpeter, may the Force (and the udoo) be with you ;)
