[GIT PULL] at91: fixes for 3.12 #2

[Nicolas Ferre]

Arnd, Olof, Kevin,

Second batch of fixes for AT91. Two little patches but that can be important
for AT91.
One is finishing the conversion to clk_xxx_[un]prepare() routines. That will
allow us to begin the move to common clock framework with help from Boris and
his big patch series. I tried to push it through Thomas and John's git tree but
without success.
The other one is important for sam9g45 when the second DDR conrtoller is in
use. The DDR / EBI lines are not properly reseted after a shutdown and could
prevent the use of whatever is connected to this EBI. It is not a configuration
that we are using on the Evaluation Kit and this explains why we face this isue
just now...

Thanks, best regards,

It sounds to me like this patch should go in together with the CCF
patches, since it doesn't address a regression and is just a
prerequisite for the conversion? If you can shake an Ack out of John
you should be all set for that. :-)

Ok, that sounds like a valid fix.

I'll cherry-pick in the DDR fix right away, and if you for some reason
need the other one we can add it later, but it sounds like it should
just go in with the CCF branch.
