Mikko Perttunen	abbdd9c844	drm/tegra: falcon: Set DMACTX field on DMA transactions ... The DMACTX field determines which context, as specified in the TRANSCFG register, is used. While during boot it doesn't matter which is used, later on it matters and this value is reused by the firmware.

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.
