3.7-stable review patch. If anyone has any objections, please let me know.
------------------ From: Aleksi Torhamo <[email protected]> commit d19528a9e4f220519c2cb3f56ef0c84ead3ee440 upstream. Fixes regression introduced in commit 70790f4f "drm/nouveau/clock: pull in the implementation from all over the place" When code was moved from nv50_crtc_set_clock to nvc0_clock_pll_set, the PLLs it is used for got limited to only the first two VPLLs. nv50_crtc_set_clock was only called to change VPLLs, so it didn't limit what it was used for in any way. Since nvc0_clock_pll_set is used for all PLLs, it has to specify which PLLs the code is used for, and only listed the first two VPLLs. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=58735 This patch is a -stable candidate for 3.7.
