2019-01-14drm/amd/display: fix compliler errors [-Werror,-Wmissing-braces]Shirish S
Initializing structures with { } is known to be problematic since it doesn't necessararily initialize all bytes, in case of padding, causing random failures when structures are memcmp(). This patch fixes the structure initialisation related compiler error by memset.

2019-01-14drm/amd/display: Compensate for XGMI SS downspread on dprefclkLeo Li
[Why] When XGMI is enabled, we need to adjust the dprefclk according to the WAFL link's spread spectrum info. This is for VG20 (DCE121) only. [How] dce_clk_mgr already stores SS info, currently being used by audio clock. Therefore, patch the clk_mgr's SS info with the xGMI SS info, if xGMI is enabled. For display clock, adjust it during dce12_update_clocks() before calling set_clock(). Since we rely on a mmhub register to reliably determine if xGMI is enabled, the patching step needs to happen after resource_construct() has initialized the hardware sequencer.

[Why] This fixes an regression introduced by: drm/amd/display: add stream ID and otg instance in dc_stream_state During driver initialization, a null pointer deref is raised. This is caused by searching for a stream status in the dc->current_state before the dc_state swap happens at the end of dc_commit_state_no_check(). Since the swap has not happened, the dc_state to be swapped in should be searched, and not dc->current_state. [How] Add a function that searches for the stream status within the given dc_state, instead of dc->current_state. Use that before the state swap happens in dc_commit_state_no_check().

2019-01-14drm/amd/display: remove sink reference in dc_stream_stateJun Lei
[why] dc_stream_state containing a pointer to sink is poor design. Sink describes the display, and the specifications or capabilities it has. That information is irrelevant for dc_stream_state, which describes hardware state, and is generally used for hardware programming. It could further be argued that dc_sink itself is just a convenience dc provides, and DC should be perfectly capable of programming hardware without any dc_sinks (for example, emulated sinks). [how] Phase 1: Deprecate use of dc_sink pointer in dc_stream. Most references are trivial to remove, but some call sites are risky (such as is_timing_changed) with no obvious logical replacement. These will be removed in follow up change. Add dc_link pointer to dc_stream. This is the typical reason DC really needed sink pointer, and most call sites are replaced with this. DMs also need minor updates, as all 3 DMs leverage stream->sink for some functionality. this is replaced instead by a pointer to private data inside dc_stream_state, which is used by DMs as a quality of life improvment for some key functionality. it allows DMs to set pointers have to their own objects which associate OS objects to dc_stream_states (such as DisplayTarget and amdgpu_dm_connector). Without the private pointer, DMs would be forced to perform a lookup for callbacks.
