2024-09-03drm/bridge-connector: move to DRM_DISPLAY_HELPER moduleDmitry Baryshkov1-0/+1
drm_bridge_connector is a "leaf" driver, belonging to the display helper, rather than the "CRTC" drm_kms_helper module. Move the driver to the drm/display and add necessary Kconfig selection clauses.

This reverts commit e075e496f516bf92bc0cbaf94d64e8d4a6b58321, as helper code should always be selected by the driver that needs it, for the convenience of the final user configuring a kernel. The user who configures a kernel should not need to know which helpers are needed for the driver he is interested in. Making a driver depend on helper code means that the user needs to know which helpers to enable first, which is very user-unfriendly.

2019-11-01drm/tegra: Unconditionally select IOMMU_IOVAThierry Reding1-1/+1
Currently configurations can be generated where IOMMU_SUPPORT is disabled but IOMMU_IOVA is built as a module and DRM_TEGRA as built-in. In such a case, the symbols guarded by IOMMU_IOVA will not be available when linking the Tegra DRM driver and cause a linking failure. Simplify this by unconditionally selecting IOMMU_IOVA, which makes sure that it will be forced to =y if DRM_TEGRA=y. Technically we can now get IOMMU_IOVA code built-in even if we don't use it (Tegra DRM only uses it when IOMMU_SUPPORT is also enabled), but such configuration are of a mostly academic nature. In all practical configurations we want IOMMU support anyway. Signed-off-by: Thierry Reding <treding@nvidia.com>

into drm-next drm/tegra: Changes for v3.13-rc1 The biggest part of the changes is the decoupling of the host1x and DRM drivers followed by the move of Tegra DRM back to drivers/gpu/drm/tegra from whence it came. There is a lot of cleanup as well, and the drivers can now be properly unloaded and reloaded. HDMI support for the Tegra114 SoC was contributed by Mikko Perttunen. gr2d support was extended to Tegra114 and the gr3d driver that has been in the works for quite some time finally made it in. All pieces to run an OpenGL driver on top of an upstream kernel are now available. Support for syncpoint bases was added by Arto Merilainen. This is useful for synchronizing between command streams from different engines such as gr2d and gr3d. Erik Faye-Lund and Wei Yongjun contributed various small fixes.

2013-03-08drm/tegra: drop "select DRM_HDMI"Paul Bolle1-1/+0
Commit ac24c2204a76e5b42aa103bf963ae0eda1b827f3 ("drm/tegra: Use generic HDMI infoframe helpers") added "select DRM_HDMI" to the DRM_TEGRA Kconfig entry. But there is no Kconfig symbol named DRM_HDMI. The select statement for that symbol is a nop. Drop it. What was needed to use HDMI functionality was to select HDMI (which this entry already did through depending on DRM) and to include linux/hdmi.h (which this commit also did).
