+ *
+ * This structure represent a modeset object property. It combines both the name
+ * of the property with the set of permissible values. This means that when a
+ * driver wants to use a property with the same name on different objects, but
+ * with different value ranges, then it must create property for each one. An
+ * example would be rotation of &drm_plane, when e.g. the primary plane cannot
+ * be rotated. But if both the name and the value range match, then the same
+ * property structure can be instantiated multiple times for the same object.
+ * Userspace must be able to cope with this and cannot assume that the same
+ * symbolic property will have the same modeset object ID on all modeset
+ * objects.
+ *
+ * Properties are created by one of the special functions, as explained in
+ * detail in the @flags structure member.
+ *
+ * To actually expose a property it must be attached to each object using
+ * drm_object_attach_property(). Currently properties can only be attached to
+ * &drm_connector, &drm_crtc and &drm_plane.
+ *
+ * Properties are also used as the generic metadatatransport for the atomic
+ * IOCTL. Everything that was set directly in structures in the legacy modeset
+ * IOCTLs (like the plane source or destination windows, or e.g. the links to
+ * the CRTC) is exposed as a property with the DRM_MODE_PROP_ATOMIC flag set.

+ * types:
+ *
+ * DRM_MODE_PROP_RANGE
+ * Range properties report their minimum and maximum admissible unsigned values.
+ * The KMS core verifies that values set by application fit in that
+ * range. The range is unsigned. Range properties are created using
+ * drm_property_create_range().
+ *
+ * DRM_MODE_PROP_SIGNED_RANGE
+ * Range properties report their minimum and maximum admissible unsigned values.
+ * The KMS core verifies that values set by application fit in that
+ * range. The range is signed. Range properties are created using
+ * drm_property_create_signed_range().
+ *
+ * DRM_MODE_PROP_ENUM
+ * Enumerated properties take a numerical value that ranges from 0 to
+ * the number of enumerated values defined by the property minus one,
+ * and associate a free-formed string name to each value. Applications
+ * can retrieve the list of defined value-name pairs and use the
+ * numerical value to get and set property instance values. Enum
+ * properties are created using drm_property_create_enum().
+ *
+ * DRM_MODE_PROP_BITMASK
+ * Bitmask properties are enumeration properties that additionally
+ * restrict all enumerated values to the 0..63 range. Bitmask property
+ * instance values combine one or more of the enumerated bits defined
+ * by the property. Bitmask properties are created using
+ * drm_property_create_bitmask().
+ *
+ * DRM_MODE_PROB_OBJECT
+ * Object properties are used to link modeset objects. This is used
+ * extensively in the atomic support to create the display pipeline,
+ * by linking &drm_framebuffer to &drm_plane, &drm_plane to
+ * &drm_crtc and &drm_connector to &drm_crtc. An object property can
+ * only link to a specific type of &drm_mode_object, this limit is
+ * enforced by the core. Object properties are created using
+ * drm_property_create_object().
+ *
+ * Object properties work like blob properties, but in a more
+ * general fashion. They are limited to atomic drivers and must have
+ * the DRM_MODE_PROP_ATOMIC flag set.
+ *
+ * DRM_MODE_PROP_BLOB
+ * Blob properties store a binary blob without any format restriction.
+ * The binary blobs are created as KMS standalone objects, and blob
+ * property instance values store the ID of their associated blob
+ * object. Blob properties are created by calling
+ * drm_property_create() with DRM_MODE_PROP_BLOB as the type.
+ *
+ * Actual blob objects to contain blob data are created using
+ * drm_property_create_blob(), or through the corresponding IOCTL.
+ *
+ * Besides the built-in limit to only accept blob objects blob
+ * properties work exactly like object properties. The only reasons
+ * blob properties exist is backwards compatibility with existing
+ * userspace.
+ *
+ * In addition a property can have any combination of the below flags:
+ *
+ * DRM_MODE_PROP_ATOMIC
+ * Set for properties which encode atomic modeset state. Such
+ * properties are not exposed to legacy userspace.
+ *
+ * DRM_MODE_PROP_IMMUTABLE
+ * Set for properties where userspace cannot be changed by
+ * userspace. The kernel is allowed to update the value of these
+ * properties. This is generally used to expose probe state to
+ * usersapce, e.g. the EDID, or the connector path property on DP

+ * @pair: pair id

+ * The term "pair" is used here, even though TLC NANDs might group pages by 3
+ * (3 bits in a single cell). A pair should regroup all pages that are sharing
+ * the same cell. Pairs are then indexed in ascending order.
+ *
+ * @group is defining the position of a page in a given pair. It can also be
+ * seen as the bit position in the cell: page attached to bit 0 belongs to
+ * group 0, page attached to bit 1 belongs to group 1, etc.
+ *
+ * Example:
+ * The H27UCG8T2BTR-BC datasheet describes the following pairing scheme:
+ *
+ * group-0 group-1
+ *
+ * pair-0 page-0 page-4
+ * pair-1 page-1 page-5
+ * pair-2 page-2 page-8
+ * ...
+ * pair-127 page-251 page-255
+ *
+ *
+ * Note that the "group" and "pair" terms were extracted from Samsung and
+ * Hynix datasheets, and might be referenced under other names in other
+ * datasheets (Micron is describing this concept as "shared pages").

+ * @get_info: converts a write-unit (page number within an erase block) into
+ * mtd_pairing information (pair + group). This function should
+ * fill the info parameter based on the wunit index or return
+ * -EINVAL if the wunit parameter is invalid.
+ * @get_wunit: converts pairing information into a write-unit (page) number.
+ * This function should return the wunit index pointed by the
+ * pairing information described in the info argument. It should
+ * return -EINVAL, if there's no wunit corresponding to the
+ * passed pairing information.
+ *
+ * See mtd_pairing_info documentation for a detailed explanation of the
+ * pair and group concepts.
+ *
+ * The mtd_pairing_scheme structure provides a generic solution to represent

+ * implement the ->get_info() and ->get_wunit() functions.
+ *
+ * MTD users will then be able to query these information by using the
+ * mtd_pairing_info_to_wunit() and mtd_wunit_to_pairing_info() helpers.
+ *
+ * @ngroups is here to help MTD users iterating over all the pages in a
+ * given pair. This value can be retrieved by MTD users using the
+ * mtd_pairing_groups() helper.

+ * affects one frame queue: @fq).
+ * 2. the QM_INITFQ_WE_CONTEXTB option of the 'we_mask' field and the associated
+ * 'fqd' structure's 'context_b' field are sometimes overwritten;
+ * - if @fq was not created with QMAN_FQ_FLAG_TO_DCPORTAL, then context_b is
+ * initialised to a value used by the driver for demux.
+ * - if context_b is initialised for demux, so is context_a in case stashing
+ * is requested (see item 4).
+ * (So caller control of context_b is only possible for TO_DCPORTAL frame queue
+ * objects.)
+ * 3. if @flags contains QMAN_INITFQ_FLAG_LOCAL, the 'fqd' structure's
+ * 'dest::channel' field will be overwritten to match the portal used to issue
+ * the command. If the WE_DESTWQ write-enable bit had already been set by the
+ * caller, the channel workqueue will be left as-is, otherwise the write-enable
+ * bit is set and the workqueue is set to a default of 4. If the "LOCAL" flag
+ * isn't set, the destination channel/workqueue fields and the write-enable bit
+ * are left as-is.
+ * 4. if the driver overwrites context_a/b for demux, then if
+ * QM_INITFQ_WE_CONTEXTA is set, the driver will only overwrite
+ * context_a.address fields and will leave the stashing fields provided by the
