In vepu_510 the sli_done interrupt is triggered by slice_fifo not empty status.Therefore when the sli_done_sta interrupt is cleared without reading all the slice_len data in slice_fifo an extra interrupt will be triggered. So it is better to clear the interrupt after reading all slice_len to avoid false irq reporting. On the other hand, vepu_580 is triggered only after writing a slice, without checking iif fifo is non-empty, so there is no need to clear the interrupt again after reading the slice Change-Id: If20a097b0e9fb41df9984c0ed316d717ba783ac4 Signed-off-by: Yanjun Liao <yanjun.liao@rock-chips.com>
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.
