commit f72b544a514c07d34a0d9d5380f5905b3731e647 upstream.
spi0_lpcg: clock-controller@5a400000 {
... Col0 Col1
clocks = <&clk IMX_SC_R_SPI_0 IMX_SC_PM_CLK_PER>,// 0 1
<&dma_ipg_clk>; // 1 4
clock-indices = <IMX_LPCG_CLK_0>, <IMX_LPCG_CLK_4>;
};
Col1: index, which existing dts try to get.
Col2: actual index in lpcg driver.
lpspi0: spi@5a000000 {
...
clocks = <&spi0_lpcg 0>, <&spi0_lpcg 1>;
^ ^
Should be:
clocks = <&spi0_lpcg IMX_LPCG_CLK_0>, <&spi0_lpcg IMX_LPCG_CLK_4>;
};
Arg0 is divided by 4 in lpcg driver. <&spi0_lpcg 0> and <&spi0_lpcg 1> are
IMX_SC_PM_CLK_PER. Although code can work, code logic is wrong. It should
use IMX_LPCG_CLK_0 and IMX_LPCG_CLK_4 for lpcg arg0.

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.
