Whenever we reset the channel, we need to clear desc_pendingcount along with desc_submitcount. Otherwise when a new transaction is submitted, the irq coalesce level could be programmed to an incorrect value in the axidma case. This behavior can be observed when terminating pending transactions with xilinx_dma_terminate_all() and then submitting new transactions without releasing and requesting the 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 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.
