To make NV12 working on icl, we need to update 2 planes simultaneously. I've chosen to do this in the CRTC step after plane validation is done, so we know what planes are (in)visible. The linked Y plane will get updated in intel_plane_update_planes_on_crtc(), by the call to update_slave, which gets the master's plane_state as argument. The link requires both planes for atomic_update to work, so make sure skl_ddb_add_affected_planes() adds both states. Changes since v1: - Introduce icl_is_nv12_y_plane(), instead of hardcoding sprite numbers. - Put all the state updating login in intel_plane_atomic_check_with_state(). - Clean up changes in intel_plane_atomic_check(). Changes since v2: - Fix intel_atomic_get_old_plane_state() to actually return old state. - Move visibility changes to preparation patch. - Only try to find a Y plane on gen11, earlier platforms only require a single plane. Changes since v3: - Fix checkpatch warning about to_intel_crtc() usage. - Add affected planes from icl_add_linked_planes() before check_planes(), it's a cleaner way to do this. (Ville) Changes since v4: - Clear plane links in icl_check_nv12_planes() for clarity. - Only pass crtc_state to icl_check_nv12_planes(). - Use for_each_new_intel_plane_in_state() in icl_check_nv12_planes. - Rename aux to linked.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
