Hi, This series intends to introduce SmartReflex AVS Class 1.5 support which is now the recommended AVS class for usage in OMAP3630, OMAP4 an potentially in later generation of silicon as well. Smartreflex class 1.5 is a software controlled hardware calibration mechanism designed to improve dvfs latencies and system performance as well as helping bring in additional benefits to the system from h/w perspective. The corresponding patch has details on this class and the implementation as well. The series eventually results in OMAP343x based platforms using class3 and OMAP3630, OMAP4 platforms using class1.5 automatically without modifications or additions to board files. This series is Based on: a) k.org 2.6.38-rc5 (b2.6.38-rc5) b) The following branches Kevin Hilman's tree: (pm-base) 'pm/for_2.6.38/pm-fixes', 'pm/for_2.6.39/pm-misc' and 'pm/pm-wip/cpufreq' http://git.kernel.org/?p=linux/kernel/git/khilman/linux-omap-pm.git;a=summary c) sr-fixes: (sr-baseline) http://marc.info/?l=linux-omap&m=129783708019505&w=2 http://marc.info/?l=linux-omap&m=129679846322563&w=2 This series is also available at: git://gitorious.org/linux-omap-nm-sr/linux-omap-sr.git Branch: sr-1.5-v1 Note: There is also a branch sr-dvfs-1.5 in my tree which contains the test version of code which is based off Vishwa's DVFS series which is currently being revamped. it may need few handtweaking for testing (esp selecting class at menuconfig level or by commenting out appropriate late_init). The series contains a bunch of bugfixes and improvements needed to introduce Smartreflex class 1.5.

Test Script: http://pastebin.mozilla.org/1080985 I request any additional tests on Panda, BeagleXM, EVM platforms that folks may have. please feel free to comment and provide tested-by/Acked-by feedback before I take this ahead including l-a.
