2020-06-10dt-bindings: display: Convert VC4 bindings to schemasMaxime Ripard
The BCM283x SoCs have a display pipeline composed of several controllers with device tree bindings that are supported by Linux. Now that we have the DT validation in place, let's split into separate files and convert the device tree bindings for those controllers to schemas. This is just a 1:1 conversion though, and some bindings were incomplete so it results in example validation warnings that are going to be addressed in the following patches.

2020-06-10drm/udl: Use GEM vmap/mmap function from SHMEM helpersThomas Zimmermann
The udl driver contains an implementation of GEM vmap and mmap operations that is identical to the common SHMEM helper; except that udl's code uses cached pages by default. Convert udl to regular SHMEM helper functions. There's no reason to have udl behave differently from all other SHMEM drivers. The udl driver uses the SHMEM helper to enable caching. v3: * rebased onto Daniel's shmem untangle series v2: * implement .gem_create_object with SHMEM helper Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200609090820.20256-3-tzimmermann@suse.de

2020-06-08drm/shmem-helpers: Simplify dma-buf importingDaniel Vetter
- Ditch the ->pages array - Make it a private gem bo, which means no shmem object, which means fireworks if anyone calls drm_gem_object_get_pages. But we've just made sure that's all covered. v2: Rebase v3: I forgot to remove the page_count mangling from the free path too. Noticed by Boris while testing.

2020-06-08drm/shmem-helpers: Ensure get_pages is not called on imported dma-bufDaniel Vetter
Just a bit of light paranoia. Also sprinkle this check over drm_gem_shmem_get_sg_table, which should only be called when exporting, same for the pin/unpin functions, on which it relies to work correctly.
