[RESEND V2 PATCH 1/3] soc/tegra: fuse: export tegra_sku_info for module use
Some Tegra drivers might be complied as kernel modules, and
they need the fuse information for initialization. One
example is the GK20A Nouveau driver. It needs the GPU speedo
value to calculate frequency-voltage table. So export
the tegra_sku_info.

[PATCH 00/15] clk/tegra: improve code and add DFS support
This series adds support for GM20B PLL's Maxwell features, namely glitchless
switch and (more importantly) DFS support. DFS lets the PLL lower its output
speed according to input current variations, making the clock more stable and
allowing it to run safely at lower voltage.
All GM20B additions are done in the last patch, which consequently ends up
being considerably big ; fortunately, it

[PATCH 00/16] clk/gm20b: add basic driver
This series does some refactoring in the GK20A's volt and clk drivers
(fixing a few things while we are at it) to let GM20B benefit from the
GK20A's logic with which it is compatible.
GM20B is capable of more sophisticated (and power-efficient) reclocking
which will follow later. Even after this more fancy reclocking is merged,
the present logic will remain used in the lowest speedo of
