From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> While looking at a regression caused by i915's use of 12bpc HDMI mode, I ended up reading the DP dual mode spec, and that lead to this patch series. I intentionally made the basics of the helper look somewhat like Thierry's HDMI 2.0 SCDC stuff [1], except with a few less bugs :P The entire series is available here: git://github.com/vsyrjala/linux.git dp_dual_mode_2 [1] https://lists.freedesktop.org/archives/dri-devel/2015-September/090929.html Ville Syrjälä (4): drm: Add helper for DP++ adaptors drm/i915: Respect DP++ adaptor TMDS clock limit drm/i915: Enable/disable TMDS output buffers in DP++ adaptor as needed drm/i915: Determine DP++ type 1 DVI adaptor presence based on VBT drivers/gpu/drm/Makefile | 2 +- drivers/gpu/drm/drm_dp_dual_mode_helper.c | 324 ++++++++++++++++++++++++++++++ drivers/gpu/drm/i915/intel_bios.h | 3 + drivers/gpu/drm/i915/intel_dp.c | 28 +++ drivers/gpu/drm/i915/intel_drv.h | 5 + drivers/gpu/drm/i915/intel_hdmi.c | 107 +++++++++- include/drm/drm_dp_dual_mode_helper.h | 80 ++++++++ 7 files changed, 540 insertions(+), 9 deletions(-) create mode 100644 drivers/gpu/drm/drm_dp_dual_mode_helper.c create mode 100644 include/drm/drm_dp_dual_mode_helper.h -- 2.4.10 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
