    drm/nouveau/kms/nv50-: Store the bpc we're using in nv50_head_atom · ac2d9275
    Lyude Paul authored
    In order to be able to use bpc values that are different from what the
    connector reports, we want to be able to store the bpc value we decide
    on using for an atomic state in nv50_head_atom and refer to that instead
    of simply using the value that the connector reports throughout the
    whole atomic check phase and commit phase. This will let us (eventually)
    implement the max bpc connector property, and will also be needed for
    limiting the bpc we use on MST displays to 8 in the next commit.
