In Gen 9 and Gen 10 platforms, async address update enable bit is
double buffered. Due to this, during the transition from async flip
to sync flip we have to wait until this bit is updated before continuing
with the normal commit for sync flip.
v9: -Rename skl_toggle_async_sync() to skl_disable_async_flip_wa(). (Ville)
-Place the declarations appropriately as per need. (Ville)
-Take the lock before the reg read. (Ville)
-Fix comment and formatting. (Ville)
-Use IS_GEN_RANGE() for gen check. (Ville)
-Move skl_disable_async_flip_wa() to intel_pre_plane_update(). (Ville)
v10: -Rebased.

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.
