* | drm/pl111: Initial drm/kms driver for pl111Tom Cooksey2017-05-081-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a modesetting driver for the pl111 CLCD display controller found on various ARM platforms such as the Versatile Express. The driver has only been tested on the bcm911360_entphn platform so far, with PRIME-based buffer sharing between vc4 and clcd. It reuses the existing devicetree binding, while not using quite as many of its properties as the fbdev driver does (those are left for future work). v2: Nearly complete rewrite by anholt, cutting 2/3 of the code thanks to DRM core's excellent new helpers. v3: Don't match pl110 any more, don't attach if we don't have a DRM panel, use DRM_GEM_CMA_FOPS, update MAINTAINERS, use the simple display helper, use drm_gem_cma_dumb_create (same as our wrapper). v4: Change the driver's .name to not clash with fbdev in sysfs, drop platform alias, drop redundant "drm" in DRM driver name, hook up .prepare_fb to the CMA helper so that DMA fences should work. v5: Move register definitions inside the driver directory, fix build in COMPILE_TEST and !AMBA mode. v6: Drop TIM2_CLKSEL for now to be consistent with existing DT bindings, switch back to external register definitions.

* | drm/doc: Add TODO listThierry Reding2017-02-071-0/+1
|/ | | | | | | | | | | | | | | | | This commit adds a TODO list to the GPU driver developer's guide. The content was taken from the DRMJanitors page on the X.Org wiki: https://www.x.org/wiki/DRMJanitors/ The goal is to track a list of refactorings that would be nice to see merged eventually. Sometimes these would be encountered during patch review on the mailing list, and at other times one can come across these while working in a specific area of code.

| * vgaarbiter: rst-ifiy and polish kerneldocDaniel Vetter2016-08-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the documentation into Documentation/gpu, link it up and pull in the kernel doc. No actual text changes except that I did polish the kerneldoc a bit, especially for vga_client_register(). v2: Remove some rst from vga-switcheroo.rst that I don't understand, but which seems to be the reason why the new vgaarbiter.rst sometimes drops out of the sidebar index. v3: Drop one level of headings and clarify the vgaarb one a bit. v4: Fix some typos (Sean).

* Documentation/gpu: add new gpu.rst converted from DocBook gpu.tmplJani Nikula2016-06-211-0/+2601
This is the first step towards converting the DocBook gpu.tmpl to Sphinx and reStructuredText, the new kernel documentation tool and markup. Use Jon's "cheesy conversion script" in Documentation/sphinx/tmplcvt to do the rough conversion. Do the manual edits in follow-up patches. Add a new Documentation/gpu directories for the graphics related documentation. (Hooray, now we can have directories based on topics rather than tools under Documentation.) We also won't remove the DocBook gpu.tmpl yet so it's easier to build both and compare the results for parity.
