[PATCH 0/7] clock/dpll autoidle support

[Rajendra Nayak]

OMAP has various clock nodes and dpll's
which support hardware level autoidle.
Enabling hardware level autoidle provides
better power savings without much software
intervention.

This series does the following to help enable
hardware level autoidling using clock framework
for some of these nodes on OMAP3 and OMAP4

-1- Adds support for providing function pointers
for enabling/disabling autoidle in clkops
-2- Populates these in clkops for all OMAP3/4 dplls
-3- Enables all dpll autoidle late in boot on OMAP3 and OMAP4
-4- Adds support for mx postdivider autoidle (present
only on OMAP4) and enables it late in OMAP4 boot

Some of the patches in this series were earlier posted
and discussed as part of another series here
http://marc.info/?l=linux-omap&m=129681356402594&w=2
They are now posted as a seperate series as discussed
here
http://marc.info/?l=linux-omap&m=129713867702170&w=2

The patches are boot tested on OMAP3430sdp and
OMAP4430sdp.
