Frank Li dc51b4442d dmaengine: fsl-edma: fix eDMAv4 channel allocation issue
The eDMAv4 channel mux has a limitation where certain requests must use
even channels, while others must use odd numbers.

Add two flags (ARGS_EVEN_CH and ARGS_ODD_CH) to reflect this limitation.
The device tree source (dts) files need to be updated accordingly.

This issue was identified by the following commit:
commit a725990557 ("arm64: dts: imx93: Fix the dmas entries order")

Reverting channel orders triggered this problem.

README

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.
