This patch adds just enough support\nto compile for Tiger Lake. Fortunately, the backlight programming\nhasn\u0027t changed since SKL, so with a little bit of hacking, one can\nalso have libgfxinit turn on the backlight to verify something is\nworking and running.\n\nThe first pass through the support will focus mostly on the eDP panel,\nthen Type-C ports (both in fixed/native mode [DP/HDMI] and in Type-C\nDP Alt Mode). TBT will not be mostly ignored in this first pass, as\nit is not as widely used (yet?) as the other protocols.\n\nThis patch includes changes to fix ironlake gnatprove errors caused by\nthe new PCH_HDMI_A port definition.\n\nTested on google/voxel, with DEBUG_ADA_CODE enabled.\nTested on google/skolas, with DEBUG_ADA_CODE enabled.\n\nThis patch leaves the following unresolved gnatprove errors:\n- hw-gfx-gma-port_detect.ads:17:14:\n     warning: subprogram \"Initialize\" has no effect\n- hw-gfx-gma-port_detect.ads:20:07:\n     warning: unused variable \"Port\"\n- hw-gfx-gma-port_detect.ads:23:14:\n     warning: subprogram \"Clear_Hotplug_Detect\" has no effect\n- hw-gfx-gma-connectors.ads:39:14:\n     warning: subprogram \"Post_Off\" has no effect\n- hw-gfx-gma-connectors.ads:42:14:\n     warning: subprogram \"Post_All_Off\" has no effect\n\nThese errors will by addressed by the proper implementation of these\nprocedures.\n\nChange-Id: I84f15837856ecc5ec8df18b39d3989885cd550d4\nSigned-off-by: Tim Wawrzynczak \u003ctwawrzynczak@chromium.org\u003e\nSigned-off-by: Jeremy Compostella \u003cjeremy.compostella@intel.com\u003e\nReviewed-on: https://review.coreboot.org/c/libgfxinit/+/70887\nTested-by: Nico Huber \u003cnico.h@gmx.de\u003e\nReviewed-by: Sean Rhodes \u003csean@starlabs.systems\u003e\nReviewed-by: Nico Huber \u003cnico.h@gmx.de\u003e\n"

      "message": "gma: Split `Internal` port type into `eDP` \u0026 `LVDS`\n\nWe used to have a single type `Internal`, in the GMA interface, to\nrepresent the port for any internal panel. This seemed suitable as\nall mainboard targets used the additional panel logic (power se-\nquencing, backlight) only with either one of the eDP and LVDS ports.\n\nHowever, the hardware allows to combine the panel logic also with\nother ports. And some of the regular DP ports are even mentioned as\nalternatives to the dedicated eDP port.\n\nAs a first step towards supporting such less common combinations,\nwe get rid of the single `Internal` type. All the panel logic still\nassumes that either the dedicated eDP or the LVDS port is used for\nan internal display. We introduce `Internal_Port_Type` to represent\neDP and LVDS, for this. But it should vanish, once the panel logic\nis adapted.\n\nChange-Id: Iadf3c11bd35d085cf47a961e800b0d96b79f62f5\nSigned-off-by: Nico Huber \u003cnico.huber@secunet.com\u003e\nReviewed-on: https://review.coreboot.org/c/libgfxinit/+/38239\nReviewed-by: Angel Pons \u003cth3fanbus@gmail.com\u003e\nTested-by: Nico Huber \u003cnico.h@gmx.de\u003e\n"

      "message": "gma: Set tiled framebuffers up through Plane_Control\n\nOn platforms with Plane_Control registers (Broxton/Skylake+) we can\nuse X and Y tiled framebuffers for scanout (older platforms support\nX tiling only). As our main use case is 90° rotation with Y tiled\nframebuffers, we implement it for the newer platforms only for now.\n\nWe also set up a fence register for linear access to the tiled frame-\nbuffer through the aperture.\n\nChange-Id: I913c82f62fd28b681a06ce13f41160a07e559799\nSigned-off-by: Nico Huber \u003cnico.h@gmx.de\u003e\nReviewed-on: https://review.coreboot.org/22709\nReviewed-by: Stefan Reinauer \u003cstefan.reinauer@coreboot.org\u003e\nTested-by: Stefan Reinauer \u003cstefan.reinauer@coreboot.org\u003e\n"
