drm/tegra: Detach devices from IOMMU DMA domain on arm32

2018-09-26T15:24:02+00:00

All Tegra DRM devices are getting attached to an implicit IOMMU DMA domain if CONFIG_ARM_DMA_USE_IOMMU=y. Since Tegra DRM driver manages IOMMU by itself, the devices must be detached from the implicit domain using arch-specific IOMMU-API. Note that this works only for arm32 and not for arm64, which will remain broken if CONFIG_IOMMU_DMA is enabled. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: Replace drm_dev_unref with drm_dev_put

2018-09-26T15:04:03+00:00

This patch unifies the naming of DRM functions for reference counting of struct drm_device. The resulting code is more aligned with the rest of the Linux kernel interfaces.

drm/tegra: sor: Add Tegra194 support

2018-09-26T14:05:09+00:00

The SOR implemented in Tegra194 is subtly different from its predecessor found in Tegra186. Most notably some registers have been moved around so it is no longer compatible. Signed-off-by: Thierry Reding

drm/tegra: dpaux: Add Tegra194 support

2018-09-26T14:04:56+00:00

The DPAUX controller found on Tegra194 is almost identical to its predecessor from Tegra186. Signed-off-by: Thierry Reding

drm/tegra: dc: Add Tegra194 support

2018-09-26T14:04:39+00:00

The display controllers found on Tegra194 are almost identical to those found on Tegra186. Signed-off-by: Thierry Reding

drm/tegra: hub: Add Tegra194 support

2018-09-26T14:04:10+00:00

The display hub integrated into Tegra194 is almost identical to the one found on Tegra186. However, it doesn't support DSC (display stream compression) so it isn't fully compatible. Signed-off-by: Thierry Reding

drm/tegra: dc: Do not register DC without primary plane

2018-09-26T14:03:51+00:00

Tegra194 contains a fourth display controller that does not own any windows. Therefore, we cannot currently assign a primary plane to it which causes KMS to eventually crash. Do not register the display controller if it owns no windows to work around this. Note that we still have to enable and probe the display controller because for some reason all display controllers need to be powered (and/or clocked) before any registers can be accessed in any of the display controllers.

drm/tegra: dpaux: Use the correct definition for pad modes

2018-09-24T13:28:42+00:00

Some of definitions in the code changed the meaning, unfortunately one place missed the change. Signed-off-by: Dmitry Osipenko Acked-by: Jon Hunter Signed-off-by: Thierry Reding

drm/tegra: Convert drm_atomic_helper_suspend/resume()

2018-09-18T14:53:54+00:00

convert drm_atomic_helper_suspend/resume() to use drm_mode_config_helper_suspend/resume(). With this conversion, tegra_drm_fb_suspend() and tegra_drm_fb_resume() will not be used anymore. Both of these functions can be removed. Also, in tegra_drm struct's member state will not be used anymore. So this can be removed forever. Fixed one sparse warning.
