This reverts commit e1a84ba8. Part of a series where patches were modified while applying to resolve conflicts, leading to further conflicts between drm-misc-next and drm-intel-next, resulting in build failures in drm-tip. To be applied again on a baseline with drm-misc-next and drm-intel-next in sync. Acked-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com>

We currently always exit that bpp loop because drm_dp_atomic_find_vcpi_slots doesn't care if we actually can fit those or not. I think that wasn't the initial intention here, especially when we keep trying with lower bpps, we are supposed to keep trying until we actually find some _working_ configuration, which isn't the case here. So added that drm_dp_mst_check here, so that we can make sure that try all the bpps before we fail.

Use a more standard form for the VT version number comments. One slight oddball case is the dp_max_link_rate that had two version numbers (216/230) and a platform name (GLK). The story goes that the field was introduced in the spec in version 216, along with a note that it's used on CNL+. Later in version 230 the definition of the bit was changed in bacakwards incompatible ways and the CNL note disappeard. For us the original CNL+ note in the header got changed to to GLK+ when all CNL support was dropped from the codebase. We do still need (and have) handling for both the 216+ and the 230+ defintions (parse_bdb_216_dp_max_link_rate() vs. parse_bdb_230_dp_max_link_rate()).

A lot of modern laptops use the Parade PS8461E MUX for eDP switching. The MUX can operate in jitter cleaning mode or redriver mode, the first one resulting in higher link quality. The jitter cleaning mode needs to know the link rate used and the MUX achieves this by snooping the LINK_BW_SET, LINK_RATE_SELECT and SUPPORTED_LINK_RATES DPCD accesses. When the MUX is powered down (seems this can happen whenever the display is turned off) it loses track of the snooped link rates so when we do the LINK_RATE_SELECT write it no longer knowns which link rate we're selecting, and thus it falls back to the lower quality redriver mode. This results in unstable high link rates (eg. usually 8.1Gbps link rate no longer works correctly). In order to avoid all that let's re-snoop SUPPORTED_LINK_RATES from the sink at the start of every link training. Unfortunately we don't have a way to detect the presence of the MUX. It looks like the set of laptops equipped with this MUX is fairly large and contains devices from multiple manufacturers. It may also still be growing with new models. So a quirk doesn't seem like a very easily maintainable option, thus we shall attempt to do this unconditionally on all machines that use LINK_RATE_SELECT. Hopefully this extra DPCD read doesn't cause issues for any unaffected machine. If that turns out to be the case we'll need to convert this into a quirk in the future.

The current scheme for generating the LFP data table pointers (when the block including them is missing from the VBT) expects the 0xffff sequence to only appear in the fp_timing terminator entries. However some VBTs also have extra 0xffff sequences elsewhere in the LFP data. When looking for the terminators we may end up finding those extra sequeneces insted, which means we deduce the wrong size for the fp_timing table. The code then notices the inconsistent looking values and gives up on the generated data table pointers, preventing us from parsing the LFP data table entirely. Let's give up on the "search for the terminators" approach and instead just hardcode the expected size for the fp_timing table. We have enough sanity checks in place to make sure we shouldn't end up parsing total garbage even if that size should change in the future (although that seems unlikely as the fp_timing and dvo_timing tables have been declared obsolete as of VBT version 229).

On some systems the panel reports alternate modes with different blanking periods. If the EDID reports them and VBT doesn't tell us otherwise then I can't really see why they should be rejected. So allow their use for the purposes of static DRRS. For seamless DRRS we still require a much more exact match of course. But that logic only kicks in when selecting the downclock mode (or in the future when determining whether we can do a seamless refresh rate change due to a user modeset).
