/**
+ * DOC: standard CRTC properties
+ *
+ * DRM CRTCs have a few standardized properties:
+ *
+ * ACTIVE:
+ * Atomic property for setting the power state of the CRTC. When set to 1
+ * the CRTC will actively display content. When set to 0 the CRTC will be
+ * powered off. There is no expectation that user-space will reset CRTC
+ * resources like the mode and planes when setting ACTIVE to 0.
+ *
+ * User-space can rely on an ACTIVE change to 1 to never fail an atomic
+ * test as long as no other property has changed. If a change to ACTIVE
+ * fails an atomic test, this is a driver bug. For this reason setting
+ * ACTIVE to 0 must not release internal resources (like reserved memory
+ * bandwidth or clock generators).
+ *
+ * Note that the legacy DPMS property on connectors is internally routed
+ * to control this property for atomic drivers.
+ * MODE_ID:
+ * Atomic property for setting the CRTC display timings. The value is the
+ * ID of a blob containing the DRM mode info. To disable the CRTC,
+ * user-space must set this property to 0.
+ *
+ * Setting MODE_ID to 0 will release reserved resources for the CRTC.
