[PATCH V2 1/4] clk: allow non-blocking for nouveau_clock_astate()
There might be some callers of nouveau_clock_astate(), and they are from
inetrrupt context. So we must ensure that this function can be atomic in
that condition. This patch adds one parameter which is subsequently passed
to nouveau_pstate_calc(). Therefore we can choose whether we want to wait
for the pstate work's completion or not.

[RFC PATCH 0/3] introduce DVFS for GK20A
Hi,
This is a try to have some simple DVFS (Dynamic Voltage and Frequency Scaling)
support for GK20A. Instead of relying on other existing frequency scaling
framework, we create a simple subdev in Nouveau for the same purpose. That's
because we don't want to make the DVFS implementation for GK20A far more
than enough in the beginning and hinder the implementation for dGPU in the
future.
