This series builds on top of David's reliable DRM minor series:
[PATCH 00/13] DRM Reliable Minor-IDs
Tegra K1 has a Kepler-type GPU without any display engine. Instead it reuses the Tegra display engine. That means that effectively the GPU becomes a render-node only device. In order to reflect that, it would be preferable for the associated /dev/dri/cardX node not to show up.
To achieve that, the DRIVER_MODESET feature needs to be removed from the GPU driver, but that unfortunately implies activating a bunch of legacy behaviour for pre-KMS drivers. To allow for drivers that don't support modesetting IOCTLs (because they drive no output) but which aren't legacy either, the meaning of the DRIVER_MODESET needs to be redefined.
This series attempts to do so by first renaming DRM_MINOR_LEGACY to DRM_MINOR_PRIMARY to more accurately reflect its purpose. Legacy and modesetting are then decoupled by introducing a DRIVER_LEGACY driver feature that can be set by truly legacy drivers. This allows the old DRIVER_MODESET feature to advertise support only for modesetting functionality, without implying that it is a non-legacy driver.
After all the drivers have been updated, the core can be modified to create the primary minor only when DRIVER_MODESET is available.
The remainder of the series cleans up some drm_core_check_feature() usage and drop some unused code related to that.
