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.
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.
Poweroff functional will be added after this basic drivers are merged.
--- Changes from v5: - pass tps6591x regulator children directly via udevice_id data field
Changes from v4: - used private structure for TPS80031 SPMS driver so that internal flags do not interfere with those from dm_regulator_uclass_plat - fixed detection on ldoln and ldousb for palmas ldo driver
Changes from v3: - expanded descriptions in Kconfigs for pmics and regulators - replaced ret with other variable name if it is not used for return - dropped prefixed with pmic name - dropped () in ~(var) type expressions - return dm_i2c_* output in pmic_read/write functions - switched to log_debug in some places - added descryptions for some "non obvious" functions - fixed tps80031 spms voltage calculation in non linear region - adjsuted tps65911 vio voltage calculation
Changes from v2: - removed all previously made poweroff API in favour to use sysreset after this patchset is accepted
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) ---
