2013-04-22regulator: palmas: Add missing ctrl_addr setting for SMPS10Axel Lin1-0/+1
The ctrl_addr setting for SMPS10 is missed, thus palmas_smps_init() read/write wrong register for SMPS10 in current code. Fix it. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2013-04-18regulator: palmas: preserve modes of rails during enable/disableLaxman Dewangan1-7/+23
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.

A lot of regulator hardware has ascendant voltage list. This patch adds regulator_map_voltage_ascend() and export it. Drivers that have ascendant voltage list can use this as their map_voltage() operation, this is more efficient than default regulator_map_voltage_iterate() function.

2013-04-17regulator: ab8500: Fix set voltage for AB8540_LDO_AUX3Axel Lin1-20/+33
When setting voltage for AB8540_LDO_AUX3, current code only updates one of info->voltage_reg and info->expand_register registers which is wrong. To ensure we set to correct voltage, it always needs to clear or set expand_register.voltage_mask bit of expand_register. The function of the expand register bit is the following (from the user manual): 0: VAUX3 output voltage is determined by Vaux3Sel bit settings in register VldoCVaux3Sel 1: VAUX3 output voltage is set to 3.05V regardless of Vaux3Sel settings in register VldoCVaux3Sel (VldoCVaux3Sel is the register at 0x0421) So when going to 3.05V, set the expand register bit. When leaving 3.05V for another voltage, set the target voltage before clearing the expand register bit.

Regulator drivers may specify regulator_desc->supply_name which regulator_register() will use to find the supply node for a regulator. If no supply was specified in the device tree or the supply has yet to be registered regulator_register() will fail, deferring the probe of the regulator.
