drm/tegra: dc: Using NULL instead of plain integer

2018-03-28T15:01:13+00:00

Fixes the following sparse warnings: drivers/gpu/drm/tegra/dc.c:2181:69: warning: Using plain integer as NULL pointer Signed-off-by: Wei Yongjun Signed-off-by: Thierry Reding

drm/tegra: dc: Use correct format array for Tegra124

2018-03-22T14:28:09+00:00

Use tegra124_(primary|overlay)_formats for Tegra124, otherwise the count specified in the Tegra124 SoC info structure will be different from the array size and cause a crash.

drm/tegra: Shutdown on driver unbind

2018-03-19T08:57:32+00:00

Since commit 846c7dfc1193 ("drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2."), removing the last framebuffer will no longer disable the corresponding pipeline, which causes the KMS core to complain about leaked connectors on driver unbind. Fix this by calling drm_atomic_helper_shutdown() on driver unbind, which will cause all display pipelines to be shut down and therefore drop the extra references on the connectors.

drm/tegra: dsi: Don't disable regulator on ->exit()

2018-03-19T08:57:28+00:00

The regulator is controlled as part of runtime PM, so it should not be additionally disabled from the ->exit() callback. Signed-off-by: Thierry Reding

drm/tegra: dc: Detach IOMMU group from domain only once

2018-03-19T08:57:04+00:00

Detaching from an IOMMU group multiple times can lead to a crash. This could potentially be fixed in the IOMMU driver, but it's easy to avoid the subsequent detach operations in this driver, so do that as well. Signed-off-by: Thierry Reding

drm/tegra: plane: Correct legacy blending

2018-03-15T14:56:46+00:00

Keep old 'dependent' state of unaffected planes, this way new state takes into account current state of unaffected planes. Fixes: ebae8d07435a ("drm/tegra: dc: Implement legacy blending") Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: plane: Fix RGB565 format on older Tegra

2018-03-15T10:33:47+00:00

The opaque/alpha format conversion code is currently only looking at XRGB formats because they have an equivalent ARGB format. The opaque format for RGB565 is RGB565 itself, much like the YUV formats map to themselves.

BackMerge tag 'v4.15-rc8' into drm-next

2018-01-17T23:32:15+00:00

Linux 4.15-rc8 Daniel requested this for so the intel CI won't fall over on drm-next so often.

Merge tag 'drm/tegra/for-4.16-rc1-fixes' of git://anongit.freedesktop.org/tegra/linux into drm-next

2018-01-12T01:46:19+00:00

drm/tegra: Changes for v4.16-rc1 The bulk of these changes are preparation work and addition of support for Tegra186. Currently only HDMI output (the primary output on Jetson TX2) is supported, but the hardware is also capable of doing DSI and DisplayPort. Tegra DRM now also uses the atomic commit helpers instead of the open- coded variant that was only doing half its job. As a bit of a byproduct of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos property support. Along the way there are also a few patches to clean up a few things and fix minor issues. * tag 'drm/tegra/for-4.16-rc1-fixes' of git://anongit.freedesktop.org/tegra/linux: (51 commits) drm/tegra: dc: Properly cleanup overlay planes drm/tegra: dc: Fix possible_crtcs mask for planes drm/tegra: dc: Restore YUV overlay support drm/tegra: dc: Implement legacy blending drm/tegra: Correct timeout in tegra_syncpt_wait drm/tegra: gem: Correct iommu_map_sg() error checking drm/tegra: dc: Link DC1 to DC0 on Tegra20 drm/tegra: Fix non-debugfs builds drm/tegra: dpaux: Keep reset defaults for hybrid pad parameters drm/tegra: Mark Tegra186 display hub PM functions __maybe_unused drm/tegra: Use IOMMU groups gpu: host1x: Use IOMMU groups drm/tegra: Implement zpos property drm/tegra: dc: Remove redundant spinlock drm/tegra: dc: Use direct offset to plane registers drm/tegra: dc: Support more formats drm/tegra: fb: Force alpha formats drm/tegra: dpaux: Add Tegra186 support drm/tegra: dpaux: Implement runtime PM drm/tegra: sor: Support HDMI 2.0 modes ...

drm/tegra: sor: Fix hang on Tegra124 eDP

2018-01-10T12:04:58+00:00

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.
