-Subject: [PATCH] kms/nv50-: Share DP SST mode_valid() handling with MST
-
-Currently, the nv50_mstc_mode_valid() function is happy to take any and
-all modes, even the ones we can't actually support sometimes like
-interlaced modes.
-
-Luckily, the only difference between the mode validation that needs to
-be performed for MST vs. SST is that eventually we'll need to check the
-minimum PBN against the MSTB's full PBN capabilities (remember-we don't
-care about the current bw state here). Otherwise, all of the other code
-can be shared.
-
-So, we move all of the common mode validation in
-nouveau_connector_mode_valid() into a separate helper,
-nv50_dp_mode_valid(), and use that from both nv50_mstc_mode_valid() and
-nouveau_connector_mode_valid(). Note that we allow for returning the
-calculated clock that nv50_dp_mode_valid() came up with, since we'll
-eventually want to use that for PBN calculation in
-nv50_mstc_mode_valid().
