include: linux: Import DRM/KMS headers from Linux v5.2
Import DRM/KMS header files from Linux kernel v5.2.
The DRM headers are used to prepare to use the DRM-defined pixel formats
(DRM_FORMAT_*) in place of the currently used V4L2 pixel formats
(V4L2_PIX_FMT_*).

This format:modifier pair must fully define the + * format and data layout of the buffer, and should be the only way to describe + * that particular buffer. + * + * Having multiple fourcc:modifier pairs which describe the same layout should + * be avoided, as such aliases run the risk of different drivers exposing + * different names for the same data format, forcing userspace to understand + * that they are aliases. + * + * Format modifiers may change any property of the buffer, including the number + * of planes and/or the required allocation size. Format modifiers are + * vendor-namespaced, and as such the relationship between a fourcc code and a + * modifier is specific to the modifer being used. For example, some modifiers + * may preserve meaning - such as number of planes - from the fourcc code, + * whereas others may not. + * + * Vendors should document their modifier usage in as much
