The SOC interrupt status register contains multiple interrupt sources (workload hint interrupt and power floor interrupt). It is not possible to clear individual interrupt source with read-modify-write, as it may clear the new interrupt from the firmware after a read operation. It is also not possible to set the interrupt status bit to 1 for the other interrupt source, which is not part of clearing. Hence, create a common function, to clear all status bits at once. Call this function after processing all interrupt sources. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> [ rjw: Changelog edits ] Signed-off-by: Rafael J.

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.
