Marek Vasut a32da24ef8 clk: imx8mp: Fix clkout1/2 support
[ Upstream commit a9b7c84d22 ]

The CLKOUTn may be fed from PLL1/2/3, but the PLL1/2/3 has to be enabled
first by setting PLL_CLKE bit 11 in CCM_ANALOG_SYS_PLLn_GEN_CTRL register.
The CCM_ANALOG_SYS_PLLn_GEN_CTRL bit 11 is modeled by plln_out clock. Fix
the clock tree and place the clkout1/2 under plln_sel instead of plain plln
to let the clock subsystem correctly control the bit 11 and enable the PLL
in case the CLKOUTn is supplied by PLL1/2/3.

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.
