kernel/linux.git/drivers/gpu/drm/tegra, branch v5.14.8

Merge tag 'drm/tegra/for-5.14-rc1' of ssh://git.freedesktop.org/git/tegra/linux into drm-next

2021-06-23T04:24:37+00:00

drm/tegra: Changes for v5.14-rc1 The two major changes here are fixed YUV support as well as scaling on Tegra186 and later. This allows Tegra DRM to be used, for example, as a video sink for the kmssink gstreamer plugin. The remainder of the changes are minor fixes.

Backmerge tag 'v5.13-rc7' into drm-next

2021-06-23T00:07:48+00:00

Backmerge Linux 5.13-rc7 to make some pulls from later bases apply, and to bake in the conflicts so far.

drm/tegra: Don't call SET_APPLICATION_ID in VIC boot

2021-06-11T16:48:36+00:00

The application should be programming the application ID, not the kernel, as there can be several options to choose from, and setting the application ID multiple times can cause issues. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

drm/tegra: Remove superfluous error messages around platform_get_irq()

2021-06-11T16:48:33+00:00

The platform_get_irq() prints error message telling that interrupt is missing,hence there is no need to duplicated that message in the drivers. Signed-off-by: Tan Zhongjun Signed-off-by: Thierry Reding

drm/tegra: hub: Implement basic scaling support

2021-05-31T12:30:11+00:00

Parameterize code in several places to allow scaling of windows. Note that this currently still relies on static programming of the various metering and memory pool allocation registers. This seems to work for the common cases, but may eventually need to be updated to support use-cases with multiple windows and higher bandwidth and latency requirements. Signed-off-by: Thierry Reding

drm/tegra: hub: Fix YUV support

2021-05-31T12:30:11+00:00

The driver currently exposes several YUV formats but fails to properly program all the registers needed to display such formats. Add the right programming sequences so that overlay windows can be used to accelerate color format conversions in multimedia playback use-cases. Signed-off-by: Thierry Reding

drm/tegra: Correct DRM_FORMAT_MOD_NVIDIA_SECTOR_LAYOUT

2021-05-31T12:29:44+00:00

The format modifier is 64bit, while DRM_FORMAT_MOD_NVIDIA_SECTOR_LAYOUT uses BIT() macro that is 32bit on ARM32. The (modifier &= ~DRM_FORMAT_MOD_NVIDIA_SECTOR_LAYOUT) doesn't work as expected on ARM32 and tegra_fb_get_tiling() fails for the tiled formats on 32bit Tegra because modifier mask isn't applied properly. Use the BIT_ULL() macro to fix this trouble. Fixes: 7b6f846785f4 ("drm/tegra: Support sector layout on Tegra194") Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: sor: Fix AUX device reference leak

2021-05-27T18:11:13+00:00

In the case where the AUX provides an I2C-over-AUX DDC channel, a reference is taken on the AUX parent device of the DDC channel rather than the DDC channel like it would be for regular I2C controllers. To make sure the correct reference is dropped, move the unreferencing code into the SOR driver and make sure not to drop the I2C adapter reference in that case. Signed-off-by: Thierry Reding

drm/tegra: Get ref for DP AUX channel, not its ddc adapter

2021-05-27T18:11:07+00:00

While we're taking a reference of the DDC adapter for a DP AUX channel in tegra_sor_probe() because we're going to be using that adapter with the SOR, now that we've moved where AUX registration happens the actual device structure for the DDC adapter isn't initialized yet. Which means that we can't really take a reference from it to try to keep it around anymore. This should be fine though, because we can just take a reference of its parent instead. v2: * Avoid calling i2c_put_adapter() in tegra_output_remove() for eDP/DP cases Signed-off-by: Lyude Paul Fixes: 39c17ae60ea9 ("drm/tegra: Don't register DP AUX channels before connectors") Cc: Lyude Paul Cc: Thierry Reding Cc: Jonathan Hunter Cc: dri-devel@lists.freedesktop.org Cc: linux-tegra@vger.kernel.org Signed-off-by: Thierry Reding

drm/tegra: Fix shift overflow in tegra_shared_plane_atomic_update

2021-05-17T10:31:05+00:00

Clang warns: drivers/gpu/drm/tegra/hub.c:513:11: warning: shift count >= width of type [-Wshift-count-overflow] base |= BIT(39); ^~~~~~~ BIT is unsigned long, which is 32-bit on ARCH=arm, hence the overflow warning. Switch to BIT_ULL, which is 64-bit and will not overflow.
