drm/tegra: Fix SMMU support on Tegra124 and Tegra210

2020-04-28T09:44:07Z

When testing whether or not to enable the use of the SMMU, consult the supported DMA mask rather than the actually configured DMA mask, since the latter might already have been restricted.

drm/tegra: hdmi: Silence deferred-probe error

2020-03-13T17:03:06Z

Driver fails to probe with -EPROBE_DEFER, which produces a bit noisy error message in KMSG during kernel's boot up. This happens because voltage regulators tend to be probed later than the DRM driver. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: dc: Silence RGB output deferred-probe error

2020-03-13T17:03:06Z

Driver fails to probe with -EPROBE_DEFER if display output isn't ready yet. This produces a bit noisy error message in KMSG during kernel's boot up on Tegra20 and Tegra30 because RGB output tends to be probed earlier than a corresponding voltage regulator driver.

drm/tegra: dc: Release PM and RGB output when client's registration fails

2020-03-12T09:26:19Z

Runtime PM and RGB output need to be released when host1x client registration fails. The releasing is missed in the code, let's correct it. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: dc: Use devm_platform_ioremap_resource

2020-03-12T09:26:02Z

The devm_platform_ioremap_resource() helper replaces few lines of a boilerplate code with a single line, making code to look cleaner a tad. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm: Remove drm_fb_helper add, add all and remove connector calls

2020-03-06T13:19:58Z

drm_fb_helper_{add,remove}_one_connector() and drm_fb_helper_single_add_all_connectors() are dummy functions now and serve no purpose. Hence remove their calls. This is the preparatory step for removing the drm_fb_helper_{add,remove}_one_connector() functions from drm_fb_helper.h This removal is done using below sementic patch and unused variable compilation warnings are fixed manually. @@ @@ - drm_fb_helper_single_add_all_connectors(...); @@ expression e1; statement S; @@ - e1 = drm_fb_helper_single_add_all_connectors(...); - S @@ @@ - drm_fb_helper_add_one_connector(...); @@ @@ - drm_fb_helper_remove_one_connector(...); Changes since v1: * Squashed warning fixes into the patch that introduced the warnings (into 5/7) (Laurent, Emil, Lyude) Signed-off-by: Pankaj Bharadiya Reviewed-by: Laurent Pinchart Reviewed-by: Emil Velikov Reviewed-by: Alex Deucher Reviewed-by: Lyude Paul Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20200305120434.111091-6-pankaj.laxminarayan.bharadiya@intel.com

drm/tegra: Reuse IOVA mapping where possible

2020-02-06T17:21:55Z

This partially reverts the DMA API support that was recently merged because it was causing performance regressions on older Tegra devices. Unfortunately, the cache maintenance performed by dma_map_sg() and dma_unmap_sg() causes performance to drop by a factor of 10. The right solution for this would be to cache mappings for buffers per consumer device, but that's a bit involved. Instead, we simply revert to the old behaviour of sharing IOVA mappings when we know that devices can do so (i.e. they share the same IOMMU domain).
