Jani Nikula ba3078dad1 drm/dp: add helpers to read link training delays ... The link training delays are different and/or available in different DPCD offsets depending on: - Clock recovery vs. channel equalization - DPRX vs. LTTPR - 128b/132b vs. 8b/10b - DPCD 1.4+ vs. earlier Add helpers to get the correct delays in us, reading DPCD if necessary. This is more straightforward than trying to retrofit the existing helpers to take 128b/132b into account. Having to pass in the DPCD receiver cap field seems unavoidable, because reading it involves checking the revision and reading extended receiver cap. So unfortunately the interface is mixed cached and read as needed. v2: Remove delay_us < 0 check and the whole local var (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211014150059.28957-1-jani.nikula@intel.com		2021-10-19 11:29:51 +03:00
