This reverts commit 773d6ea6. Since kernel 4.17 (drm/etnaviv: remove the need for a gpu-subsystem DT node) the etnaviv DRM driver doesn't have an associated DT node anymore. This is technically correct, as the etnaviv device is a virtual device driving multiple hardware devices. Before 4.17 the userspace had access to the following information: DRIVER=etnaviv OF_NAME=gpu-subsystem OF_FULLNAME=/gpu-subsystem OF_COMPATIBLE_0=fsl,imx-gpu-subsystem OF_COMPATIBLE_N=1 MODALIAS=of:Ngpu-subsystemT<NULL>Cfsl,imx-gpu-subsystem DRIVER=imx-drm OF_NAME=display-subsystem OF_FULLNAME=/display-subsystem OF_COMPATIBLE_0=fsl,imx-display-subsystem OF_COMPATIBLE_N=1 Afer 4.17: DRIVER=etnaviv MODALIAS=platform:etnaviv The OF node has never been part of the etnaviv UABI, simply due to the fact that it's still possible to instantiate the etnaviv driver from a platform file, instead of a devicetree node. A patch set to fix this problem was send out [1] but it looks like that a proper solution needs more time to bake.
