I don't really understand. Perhaps you could provide an example from one of the modules? Are you saying that you have a module that should be in a different clockdomain than the clockdomain of the module's main functional clock? > > > > > So currently, I have mentioned same entry in both the places (especially > > > > > for Peripherals/modules). > > > > > I am planning to remove ocp_if/clk entry data for all modules.. > > > > > > > > Hmmm, could you explain this further? > > > > > > what if, module only has interface clock?

Well please start with specifying the main_clk for all IP blocks. It is potentially ambiguous not to specify it, so unless there is some problem with specifying it, I'd prefer to have them. > You can access the code at - > https://github.com/hvaibhav/am335x-linux am335x-upstream-staging I'll wait until it's posted to the lists. - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
