- Convert LVDS support to a drm_bridge driver - Add DT bindings for the R8A77995 SoC - Add DT bindings and driver support for the R8A77970 SoC Note that the LVDS conversion depends on a patch series from Frank Rowand that will make it upstream through Rob Herring's tree. Frank has provided a stable branch based on v4.16-rc1 with the patches, and both Rob and I have merged it into our trees. This should thus generate no conflict when reaching -next. * 'drm/next/du' of git://linuxtv.org/pinchartl/media: dt-bindings: display: renesas: lvds: Document r8a77995 bindings dt-bindings: display: renesas: du: Document r8a77995 bindings drm: rcar-du: lvds: Add R8A77970 support drm: rcar-du: Add R8A77970 support dt-bindings: display: renesas: lvds: Document R8A77970 bindings dt-bindings: display: renesas: du: Document R8A77970 bindings drm: rcar-du: Convert LVDS encoder code to bridge driver drm: rcar-du: Fix legacy DT to create LVDS encoder nodes dt-bindings: display: renesas: Deprecate LVDS support in the DU bindings dt-bindings: display: renesas: Add R-Car LVDS encoder DT bindings of: improve reporting invalid overlay target path of: convert unittest overlay devicetree source to sugar syntax of: Documentation: of_overlay_apply() replaced by of_overlay_fdt_apply() of: change overlay apply input data from unflattened to FDT x86: devicetree: fix config option around x86_flattree_get_config()

The LVDS encoders used to be described in DT as part of the DU. They now have their own DT node, linked to the DU using the OF graph bindings. This allows moving internal LVDS encoder support to a separate driver modelled as a DRM bridge. Backward compatibility is retained as legacy DT is patched live to move to the new bindings.

The unittest-data overlays have been pulled into proper overlay devicetree source files without changing their format. The next step is to convert them to use sugar syntax instead of hand coding overlay fragments structure. A few of the overlays can not be converted because they test absolute target paths in the overlay fragment. dtc does not generate this type of target: overlay_0.dts overlay_1.dts overlay_12.dts overlay_13.dts Two pre-existing unittest overlay devicetree source files are also converted: overlay_bad_phandle.dts overlay_bad_symbol.dts Signed-off-by: -

Move duplicating and unflattening of an overlay flattened devicetree (FDT) into the overlay application code. To accomplish this, of_overlay_apply() is replaced by of_overlay_fdt_apply(). The copy of the FDT (aka "duplicate FDT") now belongs to devicetree code, which is thus responsible for freeing the duplicate FDT. The caller of of_overlay_fdt_apply() remains responsible for freeing the original FDT. The unflattened devicetree now belongs to devicetree code, which is thus responsible for freeing the unflattened devicetree. These ownership changes prevent early freeing of the duplicated FDT or the unflattened devicetree, which could result in use after free errors. of_overlay_fdt_apply() is a private function for the anticipated overlay loader. Update unittest.c to use of_overlay_fdt_apply() instead of of_overlay_apply(). Move overlay fragments from artificial locations in drivers/of/unittest-data/tests-overlay.dtsi into one devicetree source file per overlay. This led to changes in drivers/of/unitest-data/Makefile and drivers/of/unitest.c. - Add overlay directives to the overlay devicetree source files so that dtc will compile them as true overlays into one FDT data chunk per overlay. - Set CFLAGS for drivers/of/unittest-data/testcases.dts so that symbols will be generated for overlay resolution of overlays that are no longer artificially contained in testcases.dts - Unflatten and apply each unittest overlay FDT using of_overlay_fdt_apply(). - Enable the of_resolve_phandles() check for whether the unflattened overlay is detached. This check was previously disabled because the overlays from tests-overlay.dtsi were not unflattened into detached trees. - Other changes to unittest.c infrastructure to manage multiple test FDTs built into the kernel image (access by name instead of arbitrary number). - of_unittest_overlay_high_level(): previously unused code to add properties from the overlay_base devicetree to the live tree was triggered by the restructuring of tests-overlay.dtsi and thus testcases.dts. This exposed two bugs: (1) the need to dup a property before adding it, and (2) property 'name' is auto-generated in the unflatten code and thus will be a duplicate in the __symbols__ node - do not treat this duplicate as an error.

x86_flattree_get_config() is incorrectly protected by ifdef CONFIG_OF_FLATTREE. It uses of_get_flat_dt_size(), which only exists if CONFIG_OF_EARLY_FLATTREE. This issue has not been exposed previously because OF_FLATTREE did not occur unless it was selected by OF_EARLY_FLATTREE. A devicetree overlay change is selecting OF_FLATTREE directly instead of indirectly enabling it by selecting OF_EARLY_FLATTREE. This problem was exposed by a randconfig generated by the kbuild test robot, where Platform OLPC was enabled. OLPC selects OF_PROMTREE instead of OF_EARLY_FLATREE. The only other x86 platform that selects OF is X86_INTEL_CE, which does select OF_EARLY_FLATTREE. Signed-off-by:

Rather than trusting the cached value of plane_state->vma->fence to imply whether the plane_state itself holds a reference on the framebuffer's fence, use the information provided in the plane_state->flags (PLANE_HAS_FENCE). Note that we still assume that FBC is entirely bounded by the plane_state active life span; it's not clear if that is a safe assumption. Suggested-by:

Currently we make the unilateral decision inside i915_gem_object_pin_to_display() where the VMA should resided (inside the fence and mappable region or above?). This is not our decision to make as it impacts on how the display engine can use the resulting scanout object, and it would rather instruct us where to place the VMA so that it can enable the features it wants. As such, make the pin flags an argument to i915_gem_object_pin_to_display() and control them from intel_pin_and_fence_fb_obj() Whilst taking control of the mapping for ourselves, start tracking how we use it to avoid trying to free a fence we never claimed: <3>[ 227.151869] GEM_BUG_ON(vma->fence->pin_count <= 0) <4>[ 227.152064] ------------[ cut here ]------------ <2>[ 227.152068] kernel BUG at drivers/gpu/drm/i915/i915_vma.h:391! <4>[ 227.152084] invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI <0>[ 227.152092] Dumping ftrace buffer: <0>[ 227.152099] (ftrace buffer empty) <4>[ 227.152102] Modules linked in: i915 snd_hda_codec_analog snd_hda_codec_generic coretemp snd_hda_intel snd_hda_codec snd_hwdep snd_hda_core snd_pcm lpc_ich e1000e mei_me mei prime_numbers <4>[ 227.152131] CPU: 1 PID: 1587 Comm: kworker/u16:49 Tainted: G U 4.16.0-rc1-gbab67b2f6177-kasan_7+ #1 <4>[ 227.152134] Hardware name: Dell Inc.

i965 and g4x still have the pipe select bits in the plane control registers, they're just hardcoded to select a specific pipe. However plane C on i965 can still move between the pipes, thus we should program the pipe select bits on i965 if we want to expose plane C some day. Since there is no harm in programming the bits on any plane on i965/g4x let's just always set them. This will also make our pre-computed register value match what the hardware register would read, should we want to cross check the two. Signed-off-by:

G4x cursor control registers still allow us to write to the pipe select bits even though cursors are supposed to be fixed to a specific pipe. Bspec tells us that we should only ever write 0 to these bits. Let's follow that recommendation. On ilk+ the bits become hardwired to 0. Also looks like ICL repurposes these bits for some other use, so we had better stop setting them to bogus values there. Signed-off-by:

Add some compile time assrts to the frontbuffer tracking to make sure that we have enough bits per pipe to cover all the planes, and that we have enough total bits to cover all the planes across all pipes. We'll ignore any potential clash between the overlay bit and the plane bits because that will allow us to keep using a total of 32 bits for the foreseeable future. While at it change the macros to use BIT() and GENMASK(). The latter gets rid of the hardcoded 0xff and thus means we can change the number of bits per pipe by just changing INTEL_FRONTBUFFER_BITS_PER_PIPE.
