2012-02-16arm: tegra: kai: enable VDD_RTC voltage tracking to VDD_COREJohnny Qiu
With this feature enabled, VDD_RTC voltage can track to VDD_CORE while VDD_CORE voltage is higher than the default voltage of VDD_RTC, which is set to 1.0V here. When VDD_CORE is turned of in LP0, VDD_RTC keeps its default value 1.0V.
