2023-03-14drm/amd/display: convert link.h functions to function pointer styleWenjing Liu1-0/+4
[Why & How] All dc subcomponents should call another dc component via function pointers stored in a component structure. This is part of dc coding convention since the beginning. The reason behind this is to improve encapsulation and polymorphism. The function contract is extracted into a single link service structure defined in link.h header file and implemented only in link_factory.c instead of spreading across multiple files in link component file structure.

2023-03-07drm/amd/display: move dc_link functions in accessories folder to dc_link_exportsWenjing Liu1-3/+0
[why] link component should only have one interface serving dc. [how] We are moving dc_link functions exposed to DM to dc_link_exports and unify link component interface in link.h with function pointer to match the style of other dc component. This is the first step to move dc_link functions under accessories folder to dc_link_exports.

2023-02-14drm/amd/display: move public dc link function implementation to dc_link_exportsWenjing Liu1-0/+2
[why] Link is a subcomponent in dc. DM should be aware of dc link structure as one of the abstracted objects maintained by dc. However it should have no idea of the existence of a link component in dc dedicated to maintain the states of dc link structure. As such we are moving link interfaces out of dc_link.h and directly added to dc.h. We are grandually fading out the explicit inclusion of dc_link header and eventually delete it. On dc side, since link is a subcomponent behind dc interfaces, it is not a good idea to implement dc interfaces in each individual subcomponent of link which is already a subcomponent of dc. So we are decoupling it by implementing a dc_link_exports in dc. This file will be a thin translation layer that breaks the dependency so link is able to make interface changes without breaking DM.

2023-02-08drm/amd/display: break down dc_link.cWenjing Liu1-0/+29
[why] dc_link contains over 30k line of code, the decision is to break it down to files residing in link folder based on functionality. This change is the last break down change which will remove dc_link.c file after everything is broken down. [how] Move remaining dc_link.c functions into link_detection, link_dpms, link_validation, link_resource, and link_fpga and remove dc_link.
