		/**
		* DOC: overview
		*
		* In the DRM subsystem, framebuffer pixel formats are described using the
		* fourcc codes defined in `include/uapi/drm/drm_fourcc.h`. In addition to the
		* fourcc code, a Format Modifier may optionally be provided, in order to
		* further describe the buffer's format - for example tiling or compression.
		*
		* Format Modifiers
		* ----------------
		*
		* Format modifiers are used in conjunction with a fourcc code, forming a
		* unique fourcc:modifier pair. 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 detail as
		* possible, to ensure maximum compatibility across devices, drivers and
		* applications.
		*
		* The authoritative list of format modifier codes is found in
		* `include/uapi/drm/drm_fourcc.h`
