* drm/nouveau: remove symlinks, move core/ to nvkm/ (no code changes)Ben Skeggs2015-01-221-534/+0Star
| | | | | | | | | | | | The symlinks were annoying some people, and they're not used anywhere else in the kernel tree. The include directory structure has been changed so that symlinks aren't needed anymore. NVKM has been moved from core/ to nvkm/ to make it more obvious as to what the directory is for, and as some minor prep for when NVKM gets split out into its own module (virt) at a later date.

* drm/nouveau/clk: support for non-BIOS pstatesAlexandre Courbot2014-08-091-2/+2
| | | | | | | | | | | | Make nouveau_clock_create() take new two optional arguments: an array of pstates and its size. When these are specified, nouveau_clock_create() will use the provided pstates instead of probing them using the BIOS. This is useful for platforms which do not provide a BIOS, like Tegra.

* drm/nouveau/devinit: move simple pll setting routines to devinitBen Skeggs2013-07-011-35/+0Star
| | | | | | | | | These are pretty much useless for reclocking purposes. Lets make it clearer what they're for and move them to DEVINIT to signify they're for the very simple PLL setting requirements of running the init tables. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
