The edma feature individual IRQs for each DMA channel at some devices. Given the presence of numerous eDMA instances, each with multiple channels, IRQ request during probe results in an extensive list at /proc/interrupts. However, a significant portion of these channels remains unused by the system. Request irq only when a DMA client driver requests a DMA channel.

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 reStructuredText 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.
