commit 1d86c2b3946e69d6b0b93568d312aae6247847c0 upstream.
lpcg's arg0 should use clock indices instead of index.
pwm0_lpcg: clock-controller@5d400000 {
... // Col1 Col2
clocks = <&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>, // 0 0
<&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>, // 1 1
<&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>, // 2 4
<&lsio_bus_clk>, // 3 5
<&clk IMX_SC_R_PWM_0 IMX_SC_PM_CLK_PER>; // 4 6
clock-indices = <IMX_LPCG_CLK_0>, <IMX_LPCG_CLK_1>,
<IMX_LPCG_CLK_4>, <IMX_LPCG_CLK_5>,
<IMX_LPCG_CLK_6>;
};
Col1: index, which existing dts try to get.
Col2: actual index in lpcg driver.
pwm1 {
....
clocks = <&pwm1_lpcg 4>, <&pwm1_lpcg 1>;
^^ ^^
should be:
clocks = <&pwm1_lpcg IMX_LPCG_CLK_6>, <&pwm1_lpcg IMX_LPCG_CLK_1>;
};
Arg0 is divided by 4 in lpcg driver, so index 0 and 1 will be get by pwm
driver, which are same as IMX_LPCG_CLK_6 and IMX_LPCG_CLK_1. Even it can
work, but code logic is wrong. Fixed it by use correct 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.
