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.
