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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
