Based on the platform, Bspec expects us to wait or poll with timeout for DDI BUF IDLE bit to be set to 0 (non idle) or get active after enabling DDI_BUF_CTL. v2: * Based on platform, fixed delay or poll (Ville) * Use a helper to do this (Imre, Ville) v3: * Add a new function _active for DDI BUF CTL to be non idle (Ville) v4: * Use the timeout for GLK (Ville) v5: * Add bspec quote, change timeout to 500us (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Imre Deak <imre.deak@intel.com> Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200701221052.8946-2-manasi.d.navare@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.
