[PATCH 0/3] sta2x11 common clock framework implementation

[Davide Ciminaghi <ciminaghi@gnudd.com>]

Hi,

this patchset is the first implementation of the common clock framework for
the STA2X11 (aka connext) chip.

Actually 1/3 and 2/3 are not strictly relevant to the clock framework, but
they're needed to get the rest of the code to compile and have already
been submitted some months ago (see https://lkml.org/lkml/2012/9/20/363)
and acked by Alessandro Rubini (see https://lkml.org/lkml/2012/9/20/452).

3/3 has been submitted RFC on Jun 20th 2012
(see https://lkml.org/lkml/2012/6/20/779).
Mike Turquette reviewed it (see https://lkml.org/lkml/2012/8/23/624) and
his comments have been taken into account for this submission.

Please note that this patchset applies to next-20130307, should build cleanly
and do no harm at runtime, but it is not functional because it needs the
pci-to-amba bridge patch by Alessandro Rubini, which has already been
submitted several times but has not made it in the linux-next tree
yet (see thread https://lkml.org/lkml/2013/2/20/561 for more details).

Some clocks still have to be added and some others need to be implemented
with different types (see the TODOs in the code), but the current
implementation is actually enough to get a Connext based board up and running
(with its UARTs working at least), of course provided that the pci to
amba bridge is there. Multiple instances of the Connext chip should also be
supported, even if no test has been done up to now.

Thanks and regards
Davide
