+
+/* FILE POLICY AND INTENDED USAGE:
+ *
+ * This header defines link component function interfaces aka link_service.
+ * link_service provides the only entry point to link functions with function
+ * pointer style. This header is strictly private in dc and should never be
+ * included by DM because it exposes too much dc detail including all dc
+ * private types defined in core_types.h. Otherwise it will break DM - DC
+ * encapsulation and turn DM into a maintenance nightmare.
+ *
+ * The following shows a link component relation map.
+ *
+ * DM to DC:
+ * DM includes dc.h
+ * dc_link_exports.c or other dc files implement dc.h
+ *
+ * DC to Link:
+ * dc_link_exports.c or other dc files include link.h
+ * link_factory.c implements link.h
+ *
+ * Link sub-component to Link sub-component:
+ * link_factory.c includes --> link_xxx.h
+ * link_xxx.c implements link_xxx.h
+
+ * As you can see if you ever need to add a new dc link function and call it on
+ * DM/dc side, it is very difficult because you will need layers of translation.
+ * The most appropriate approach to implement new requirements on DM/dc side is
+ * to extend or generalize the functionality of existing link function
+ * interfaces so minimal modification is needed outside link component to
+ * achieve your new requirements. This approach reduces or even eliminates the
+ * effort needed outside link component to support a new link feature. This also
+ * reduces code discrepancy among DMs to support the same link feature. If we
+ * test full code path on one version of DM, and there is no feature specific
+ * modification required on other DMs, then we can have higher confidence that
+ * the feature will run on other DMs and produce the same result. The following
+ * are some good examples to start with:
+ *
+ * - detect_link --> to add new link detection or capability retrieval routines
+ *
+ * - validate_mode_timing --> to add new timing validation conditions
+ *
+ * - set_dpms_on/set_dpms_off --> to include new link enablement sequences
+ *
+ * If you must add new link functions, you will need to:
+ * 1. declare the function pointer here under the suitable commented category.
+ * 2. Implement your function in the suitable link_xxx.c file.
+ * 3. Assign the function to link_service in link_factory.c
+ * 4. NEVER include link_xxx.h headers outside link component.
+ * 5. NEVER include link.h on DM side.
