Patch set adds basic support for PMICs used in many Tegra 3 devices. All PMIC drivers are based on datasheets provided by vendors. Implemented API include regulator set/get voltage enable/disable and basic PMIC r/w capabilities.
Created poweroff API for pmic to be able to call do_poweroff directly from within pmic driver. PMIC responcible for poweroff shoud be marked as system-power-controller in device tree.
Drivers were tested by me on LG P895 (max77663), HTC One X (TPS80032) and ASUS TF300T (tps65911). Calculations and behavior were correct, predictable and reproducible.
--- Changes from v1: - created poweroff API for PMIC and integrated it call into do_poweroff - added poweroff function to submitted max77663, tps80032 and tps65911 drivers - fixed registers asignments for regulators with non-numeric name (ldoln, ldousb, vddctrl) ---
