Thanks for the merge. We don't have any further plans of pursuing the concept of regulator chaining for upstream. After an off-line chat with Mike T, we are planning on introducing OMAP specific notifier hooks to clock framework. This should allow us to do the appropriate sequencing necessary to control AVS, regulators for ABB and PMIC in the right sequence. -- Regards, Nishanth Menon
