The busy timeout logic checks for the AUX BUSY, then waits for the timeout period and then after timeout reads the register for BUSY or Success. Instead replace interrupt with polling so as to read the AUX CTL register often before the timeout period. Looks like there might be some issue with interrupt-on-read. Hence changing the logic to polling read. v2: replace interrupt with polling read v3: use usleep_rang instead of msleep, updated commit msg v4: use intel_wait_for_regiter internal function v5: use __intel_de_wait_for_register with 500us slow and 10ms fast timeout v6: check return value of __intel_de_wait_for_register v7: using default 2us for intel_de_wait_for_register Signed-off-by: Arun R Murthy <arun.r.murthy@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221221033209.1284435-1-arun.r.murthy@intel.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.
