It might be too late for 3.3 :( The following two patch will optimize the PLL configuration code for the twl6040, so if the requested configuration is the same as the current we simply skip configuring the PLL (since no change needed). We can save considerable amount of time in this way (due to avoiding i2c accesses, and delays dictated by the configuration protocol).
