Lyude Paul	b66f51710d	UPSTREAM: drm/tegra: Don't register DP AUX channels before connectors ... As pointed out by the documentation for drm_dp_aux_register(), drm_dp_aux_init() should be used in situations where the AUX channel for a display driver can potentially be registered before it's respective DRM driver. This is the case with Tegra, since the DP aux channel exists as a platform device instead of being a grandchild of the DRM device. Since we're about to add a backpointer to a DP AUX channel's respective DRM device, let's fix this so that we don't potentially allow userspace to use the AUX channel before we've associated it with it's DRM connector.

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.
