2022-01-10drm: bridge: adv7511: Fix ADV7535 HPD enablementJagan Teki
Existing HPD enablement logic is not compatible with ADV7535 bridge, thus any runtime plug-in of HDMI cable is not working on these bridge designs. Unlike other ADV7511 family of bridges, the ADV7535 require HPD_OVERRIDE bit to set and reset for proper handling of HPD functionality. Fix it.

2022-01-06drm: omapdrm: Fix implicit dma_buf fencingIvaylo Dimitrov
Currently omapdrm driver does not initialize dma_buf_export_info resv member, which leads to a new dma_resv being allocated and attached to the exported dma_buf. This leads to the issue that fences created on dma_buf objects imported by other drivers are ignored by omapdrm, as only fences in gem object resv are waited on. This leads to various issues like displaying incomplete frames. Fix that by initializing dma_buf resv to the resv of the gem object being exported.

2022-01-06drm/plane: Make format_mod_supported truly optionalJosé Expósito
The documentation for "drm_plane_funcs.format_mod_supported" reads: This *optional* hook is used for the DRM to determine if the given format/modifier combination is valid for the plane. This allows the DRM to generate the correct format bitmask (which formats apply to which modifier), and to validate modifiers at atomic_check time. *If not present*, then any modifier in the plane's modifier list is allowed with any of the plane's formats. However, where the function is not present, an invalid IN_FORMATS blob property with modifiers but no formats is exposed to user-space. This breaks the latest Weston [1]. For testing purposes, I extracted the affected code to a standalone program [2]. Make "create_in_format_blob" behave as documented.

2022-01-05drm/bridge: parade-ps8640: Link device to ensure suspend/resume orderAngeloGioacchino Del Regno
Entering suspend while the display attached to this bridge is still on makes the resume sequence to resume the bridge first, display last: when this happens, we get a timeout while resuming the bridge, as its MCU will get stuck due to the display being unpowered. On the other hand, on mt8173-elm, closing the lid makes the display to get powered off first, bridge last, so at resume time the sequence is swapped (compared to the first example) and everything just works as expected. Add a stateless device link to the DRM device that this bridge belongs to, ensuring a correct resume sequence and solving the unability to correctly resume bridge operation in the first mentioned example.

2021-12-16drm/vmwgfx: Fix possible usage of an uninitialized variableZack Rusin
vmw_user_bo_lookup can fail to lookup user buffers, especially because the buffer handles come from the userspace. The return value has to be checked before the buffers are put back. This was spotted by Dan's Smatch statick checker: drivers/gpu/drm/vmwgfx/vmwgfx_bo.c:574 vmw_user_bo_synccpu_release() error: uninitialized symbol 'vmw_bo'.

2021-12-16drm/vmwgfx: Remove unused compile optionsZack Rusin
Before the driver had screen targets support we had to disable explicit bringup of its infrastructure because it was breaking screen objects support. Since the implementation of screen targets landed there hasn't been a reason to explicitly disable it and the options were never used. Remove of all that unused code.

2021-12-16drm/vmwgfx: Remove explicit transparent hugepages supportZack Rusin
Old versions of the svga device used to export virtual vram, handling of which was optimized on top of transparent hugepages support. Only very old devices (OpenGL 2.1 support and earlier) used this code and at this point performance differences are negligible. Because the code requires very old hardware versions to run it has been largely untested and unused for a long time. Furthermore removal of the ttm hugepages support in: commit 0d979509539e ("drm/ttm: remove ttm_bo_vm_insert_huge()") broke the coherency mode in vmwgfx when running with hugepages.

2021-12-16drm/vmwgfx: Fix a size_t/long int format specifier mismatchZack Rusin
On i386 size_t is of course 32bits and using long int throws warnings, trivially fix it by using the dedicated size_t format.
