From: Frank Li Frank.Li@nxp.com
commit 808e7716edcdb39d3498b9f567ef6017858b49aa upstream.
usb2_lpcg: clock-controller@5b270000 { ... Col1 Col2 clocks = <&conn_ahb_clk>, <&conn_ipg_clk>; // 0 6 clock-indices = <IMX_LPCG_CLK_6>, <IMX_LPCG_CLK_7>; // 0 7 ... };
Col1: index, which existing dts try to get. 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.
