drm/tegra: Move subdevice infrastructure to host1x 2013-10-31T08:55:33+00:00 Thierry Reding treding@nvidia.com 2013-10-14T12:43:22+00:00 776dc38403676f499a73d32e2e7c61eb5b42f736 The Tegra DRM driver currently uses some infrastructure to defer the DRM core initialization until all required devices have registered. The same infrastructure can potentially be used by any other driver that requires more than a single sub-device of the host1x module. Make the infrastructure more generic and keep only the DRM specific code in the DRM part of the driver. Eventually this will make it easy to move the DRM driver part back to the DRM subsystem.
