Checks the pixel blending mode and plane alpha value when do the plane_check. Mali DP supports blending the current plane with the background either based on the pixel alpha blending mode or by using the layer's alpha value, but not both at the same time. If both case, plane_check will return failed. Sets the HW when doing plane_update accordingly. If plane alpha is the 0xffff, set the pixel blending bits accordingly. If not we'd set ALPHA bit as zero and layer alpha value. Changes since v1: - Introduces to use it in the malidp driver, which depends on the plane alpha patch Changes since v2: - Refines the comments of drm/mali-dp patchset Changes since v3: - Adds hardware limitation check Changes since v4: - Updates on drm/malidp, hardware limitation check only when the format has alpha pixel. - Rebases on drm-misc-next.

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.
