Thierry Reding	756aa327f1	drm/tegra: Implement correct DMA-BUF semantics ... DMA-BUF requires that each device that accesses a DMA-BUF attaches to it separately. To do so the host1x_bo_pin() and host1x_bo_unpin() functions need to be reimplemented so that they can return a mapping, which either represents an attachment or a map of the driver's own GEM object.

Jon Hunter	b8c2d943ed	drm/tegra: Add upstream tegra-drm driver ... Add the upstream tegra-drm driver with the 'Host1x/Tegra UAPI' series [0] applied. This driver will be built as an external module for testing and development with upstream Linux kernels. The following modifications have been made to the series posted upstream 1. Update the Makefile to always build the driver as a module 2. Always enable the tegra_drm_ioctl_xxx in the tegra_drm_ioctls and remove the dependency on CONFIG_DRM_TEGRA_STAGING. 3. Rename the include/uapi/drm/tegra_drm.h to include/uapi/drm/tegra_drm_next.h to avoid conflicts with upstream headers when building as an external module. 5. Rename the module that is built to be tegra-drm-next.ko instead of tegra-drm.ko to avoid any depmod conflicts with the upstream driver.
