This signal controls the secure-mode operation of the PMIC. If its not mux'd correctly, some functionality of the PMIC will not be accessible since the PMIC will be in secure mode. For example, if the TWL RTC is in secure mode, most of its registers are read-only, meaning (re)programming the RTC (e.g. for wakeup from suspend) will fail. To fix, ensure the signal is properly mux'd as output when TWL is intialized. This fix is required when using recent versions of u-boot (>= v2012.04.01) since u-boot is no longer setting the default mux for this pin.
