2018-02-02drm/i915/dp: limit DP link rate based on VBT on CNL+Jani Nikula
We have the max DP link rate info available in VBT since BDB version 216, included in child device config since commit c4fb60b9aba9 ("drm/i915/bios: add DP max link rate to VBT child device struct").

2018-01-19drm/i915/cnl: Add Port F definition.Rodrigo Vivi
Some Cannonlake SKUs will come with a full split between port A and port E. This will be called port F although it is not a 6th port, but only a split. Note this patch alone is not sufficient for port F enabling, it's just the first step. v2: Fix size of dvo_ports found by Ander. v3: Adding missing cases from intel_bios.c for Port_F v4: Adding other missing cases and fix the commit message. v5: Rebase on top of display headers rework. v6 (from Paulo): improve commit message, bikeshed bit definitions.

2016-11-14drm/i915: Assume non-DP++ port if dvo_port is HDMI and there's no AUX ch ↵Ville Syrjälä
specified in the VBT My heuristic for detecting type 1 DVI DP++ adaptors based on the VBT port information apparently didn't survive the reality of buggy VBTs. In this particular case we have a machine with a natice HDMI port, but the VBT tells us it's a DP++ port based on its capabilities. The dvo_port information in VBT does claim that we're dealing with a HDMI port though, but we have other machines which do the same even when they actually have DP++ ports. So that piece of information alone isn't sufficient to tell the two apart. After staring at a bunch of VBTs from various machines, I have to conclude that the only other semi-reliable clue we can use is the presence of the AUX channel in the VBT. On this particular machine AUX channel is specified as zero, whereas on some of the other machines which listed the DP++ port as HDMI have a non-zero AUX channel. I've also seen VBTs which have dvo_port a DP but have a zero AUX channel. I believe those we need to treat as DP ports, so we'll limit the AUX channel check to just the cases where dvo_port is HDMI. If we encounter any more serious failures with this heuristic I think we'll have to have to throw it out entirely. But that could mean that there is a risk of type 1 DVI dongle users getting greeted by a black screen, so I'd rather not go there unless absolutely necessary. v2: Remove the duplicate PORT_A check (Daniel) Fix some typos in the commit message Cc: Daniel Otero <daniel.otero@outlook.com> Cc: stable@vger.kernel.org Tested-by: Daniel Otero <daniel.otero@outlook.com> Fixes: d61992565bd3 ("drm/i915: Determine DP++ type 1 DVI adaptor presence based on VBT") Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97994 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1478884464-14251-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2016-06-02drm/i915: Extract physical display dimensions from VBTVille Syrjälä
The VBT has these mysterious H/V image sizes as part of the display timings. Looking at some dumps those appear to be the physical dimensions in mm. Which makes sense since the timing descriptor matches the format used by EDID detailed timing descriptor, which defines these as "H/V Addressable Video Image Size in mm". So let's use that information from the panel fixed mode to get the physical dimensions for LVDS/eDP/DSI displays.
