RESEND Preparations for Fermi DRAM clock changes
Two patches went missing as a result of PEBCAK. No v2 marks as nothing
changed really. Just resending for easier enforcement of patch order
in other people's trees. Sorry for the noise.
Original message:
No, no, these will not implement Fermi reclocking. This set of patches
contains some of the preparatory work that I deem stable enough to
move upstream. Notable changes

No, no, these will not implement Fermi reclocking. This set of patches
contains some of the preparatory work that I deem stable enough to
move upstream. Notable changes
- Training pattern upload routines from GK104+ now shared with GT215+
- Timing calculation for Fermi
- GDDR5 MR calculation from VBIOS timing table v1.0. Also useful for that
pesky GT 240.
- A routine to translate a VBIOS init

[PATCH 0/2] Some minor reclocking fixes
First patch fixes a potential vbios parsing bug on Fermi GPUs, but it may
also affect Kepler ones.
Second patch wakes the GPU up whenever the user tries to reclock to
prevent the write to the pstate file from freezing.

This series fixes most of the issues regarding volting on GPUs with any form

[PATCH 0/9] Groundwork for clocking fixes
This series contains a lot of groundwork to finally fix reclocking issues on
Kepler+ gpus.
There shouldn't be any functional changes with the first patch being the only
exception (fixes some voltage table parsing issues with of few kepler gpus)
The most interessting thing is the tool in the last patch, which can be ran
alongside the nvidia driver to test nouveaus volting code and print the
