2018-01-10drm/msm/gpu: Remove unused bus scaling codeJordan Crouse
Remove the downstream bus scaling code. It isn't needed for for compatibility with a downstream or vendor kernel. Get it out of the way to clear space for devfreq support. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

2018-01-10drm/tegra: sor: Fix hang on Tegra124 eDPThierry Reding
The SOR0 found on Tegra124 and Tegra210 only supports eDP and LVDS and therefore has a slightly different clock tree than the SOR1 which does not support eDP, but HDMI and DP instead. Commit e1335e2f0cfc ("drm/tegra: sor: Reimplement pad clock") breaks setups with eDP because the sor->clk_out clock is uninitialized and therefore setting the parent clock (either the safe clock or either of the display PLLs) fails, which can cause hangs later on since there is no clock driving the module. Fix this by falling back to the module clock for sor->clk_out on those setups. This guarantees that the module will always be clocked by an enabled clock and hence prevents those hangs.

2018-01-09drm/vmwgfx: Don't cache framebuffer mapsThomas Hellstrom
Buffer objects need to be either pinned or reserved while a map is active, that's not the case here, so avoid caching the framebuffer map. This will cause increasing mapping activity mainly when we don't do page flipping. This fixes occasional garbage filled screens when the framebuffer has been evicted after the map. Since in-kernel mapping of whole buffer objects is error-prone on 32-bit architectures and also quite inefficient, we will revisit this later.

2018-01-08drm/tegra: dc: Restore YUV overlay supportThierry Reding
Commit ebae8d07435a ("drm/tegra: dc: Implement legacy blending") broke support for YUV overlays by accident. The reason is that YUV formats are considered opaque because they have no alpha component, but on the other hand no corresponding format with an alpha component can be returned. In the case of YUV formats, the opaque format is the same as the alpha format, so add the special case to restore YUV overlay support.

git://git.armlinux.org.uk/~rmk/linux-arm into drm-next This series builds upon the set of fixes previously submitted to move Armada DRM closer to atomic modeset. We're nowhere near yet, but this series helps to get us closer by unifying some of the differences between the primary and overlay planes. New features added allows userspace to disable the primary plane if overlay is full screen and there's nothing obscuring the colorkey - this saves having to fetch an entire buffer containing nothing but colorkey when displaying full screen video.

drm-next Highlights this time: 1. Fix for a nasty Kconfig dependency chain issue from Philipp. 2. Occlusion query buffer address added to the cmdstream validator by Christian. 3. Fixes and cleanups to the job handling from me. This allows us to turn on the GPU performance profiling added in the last cycle. It is also prep work for hooking in the DRM GPU scheduler, which I hope to land for the next cycle. * 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux: (32 commits) drm/etnaviv: use memset32 to init pagetable drm/etnaviv: move submit free out of critical section drm/etnaviv: re-enable perfmon support drm/etnaviv: couple runtime PM management to submit object lifetime drm/etnaviv: move GPU active handling to bo pin/unpin drm/etnaviv: move cmdbuf into submit object drm/etnaviv: use submit exec_state for perfmon sampling drm/etnaviv: move exec_state to submit object drm/etnaviv: move PMRs to submit object drm/etnaviv: refcount the submit object drm/etnaviv: move ww_acquire_ctx out of submit object drm/etnaviv: move object unpinning to submit cleanup drm/etnaviv: attach in fence to submit and move fence wait to fence_sync drm/etnaviv: rename submit fence to out_fence drm/etnaviv: move object fence attachment to gem_submit path drm/etnaviv: simplify submit_create drm/etnaviv: add lockdep annotations to buffer manipulation functions drm/etnaviv: hold GPU lock while inserting END command drm/etnaviv: move workqueue to be per GPU drm/etnaviv: remove switch_context member from etnaviv_gpu ...

2018-01-04drm/i915: Apply Display WA #1183 on skl, kbl, and cflLucas De Marchi
Display WA #1183 was recently added to workaround "Failures when enabling DPLL0 with eDP link rate 2.16 or 4.32 GHz and CD clock frequency 308.57 or 617.14 MHz (CDCLK_CTL CD Frequency Select 10b or 11b) used in this enabling or in previous enabling." This workaround was designed to minimize the impact only to save the bad case with that link rates. But HW engineers indicated that it should be safe to apply broadly, although they were expecting the DPLL0 link rate to be unchanged on runtime. We need to cover 2 cases: when we are in fact enabling DPLL0 and when we are just changing the frequency with small differences.

The msm/kms driver should work even if there is no GPU device specified in DT. Currently, we get a NULL dereference crash in adreno_load_gpu since the driver assumes that priv->gpu_pdev is non-NULL. Perform an additional check on priv->gpu_pdev before trying to retrieve the msm_gpu pointer from it. v2: Incorporate Jordan's comments: - Simplify the check to share the same error message. - Use dev_err_once() to avoid an error message every time we open the drm device fd.

This updates the compatible string for a no-name LCD panel to "vot,v220hf01a-t", "ilitek,ili9225". The original bindings were the generic "ilitek,ili9225-2.2in-176x220" because I could not find a datasheet. However, after some more research, I finally found one, so the actual vendor and model name are now known.
