2026-07-28drm/amd/display: add FreeSync/VRR moduleAlex Hung
[WHAT] Group the FreeSync/VRR helpers from amdgpu_dm.c into a dedicated amdgpu_dm_freesync.c and amdgpu_dm_freesync.h. The moved functions are: is_dc_timing_adjust_needed, is_timing_unchanged_for_freesync, set_freesync_fixed_config, reset_freesync_config_for_crtc, get_freesync_config_for_crtc, update_freesync_state_on_stream, update_stream_irq_parameters, amdgpu_dm_handle_vrr_transition. The FreeSync/VRR helpers exposed by amdgpu_dm_freesync.h are called from amdgpu_dm.c, so give the seven that lacked a namespace prefix the standard amdgpu_dm_ prefix: Relocate the corresponding KUnit tests into amdgpu_dm_freesync_test.c. No functional change.
