153 	 * planes on the same CRTC have identical zpos values. This is a
166 	 * number of active planes for given crtc. Note that the driver must set
332 	 * with the frame buffer ID set to 0.  Disabled planes must not be
557  * For historical reasons not all planes are made the same. This enumeration is
558  * used to tell the different types of planes apart to implement the different
560  * which is using that atomic IOCTL there's no difference between these planes
563  * For compatibility with legacy userspace, only overlay planes are made
580 	 * Overlay planes represent all non-primary, non-cursor planes. Some
581 	 * drivers refer to these types of planes as "sprites" internally.
610  * Planes represent the scanout hardware of a display block. They receive their
611  * input data from a &drm_framebuffer and feed it to a &drm_crtc. Planes control
