Col2: actual index in lpcg driver. usbotg1: usb@5b0d0000 { ... clocks = <&usb2_lpcg 0>; ^^ Should be: clocks = <&usb2_lpcg IMX_LPCG_CLK_6>; }; usbphy1: usbphy@5b100000 { clocks = <&usb2_lpcg 1>; ^^ SHould be: clocks = <&usb2_lpcg IMX_LPCG_CLK_7>; }; Arg0 is divided by 4 in lpcg driver. So lpcg will do dummy enable. Fix it by use correct clock indices.
