drm/nouveau: fix bogus GPL-2 license header The bulk SPDX addition made all these files into GPL-2.0 licensed files. However the remainder of the project is MIT-licensed, these files (primarily header files) were simply missing the boiler plate and got caught up in the global update.

drm/nouveau/mc: namespace + nvidia gpu names (no binary change) The namespace of NVKM is being changed to nvkm_ instead of nouveau_, which will be used for the DRM part of the driver. This is being done in order to make it very clear as to what part of the driver a given symbol belongs to, and as a minor step towards splitting the DRM driver out to be able to stand on its own (for virt). Because there's already a large amount of churn here anyway, this is as good a time as any to also switch to NVIDIA's device and chipset naming to ease collaboration with them. A comparison of objdump disassemblies proves no code changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> 2015-01-14 15:08:21 +10:00			`#ifndef __NVKM_MC_H__`

drm/nouveau/mc: expose device enable/disable separately, as well as reset There are cases where subdevs need to perform additonal actions around the master reset, so we want to expost the operations separately. This commit also adds a flag to the NV_PMC_ENABLE bitfield definitions which allow skipping the automatic reset() called from core/subdev.c.
