31 * This header defines link component function interfaces aka link_service.
32 * link_service provides the only entry point to link functions with function
38 * The following shows a link component relation map.
44 * DC to Link:
45 * dc_link_exports.c or other dc files include link.h
46 * link_factory.c implements link.h
48 * Link sub-component to Link sub-component:
52 * As you can see if you ever need to add a new dc link function and call it on
55 * to extend or generalize the functionality of existing link function
56 * interfaces so minimal modification is needed outside link component to
58 * effort needed outside link component to support a new link feature. This also
59 * reduces code discrepancy among DMs to support the same link feature. If we
65 * - detect_link --> to add new link detection or capability retrieval routines
69 * - set_dpms_on/set_dpms_off --> to include new link enablement sequences
71 * If you must add new link functions, you will need to:
75 * 4. NEVER include link_xxx.h headers outside link component.
76 * 5. NEVER include link.h on DM side.
