The Palma device like TPS65913 have the mode mask which is also used for enable/disable the rails. The mode bits are defined as 00: OFF 01: AUTO 10: ECO 11: Forced PWM and modes are set accordingly as REGULATOR_MODE_NORMAL: AUTO REGULATOR_MODE_IDLE: ECO REGULATOR_MODE_FAST: PWM Two issue observed: 1. If client calls following sequence: regulator_enable(), regulator_set_mode(FAST), regulator_disable() and again the regulator_enable() then the mode is reset to NORMAL inplace of keeping the mode as FAST. Fixing this by storing the current mode configured by client and restoring modes when enable() is called after disable(). 2. In following sequence, the regulator get enabled: regulator_disable() regulator_set_mode(FAST), Fixing this by updating new mode in register only if it is enabled.
