2013-04-03ARM: ux500: Pass regulator platform data using the new formatLee Jones
Regulator platform data is now passed though a single structure as opposed to the old way where four separate struct elements were required. This patch makes use of the new format. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-04-03regulator: ab8500: Use regulator_list_voltage_table() to look-up voltagesLee Jones
The regulator framework offers a generic regulator_list_voltage_table() function which can directly look-up a regulator's voltage capabilities using a table provided through the desc structure. This patch ensures that information is available. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-04-03regulator: ab8500: Remove the need for a 'delay' propertyLee Jones
The regulator framework now has provisions to read a regulator's start-up time via the 'enable_time' attribute. So let's remove all 'enable_time'/'delay' duplication and just stick with 'enable_time' from now on.

2013-04-03regulator: ab8500: Set enable enable_time in regulator_descLee Jones
Allow the regulator framework to directly access the time it takes any given regulator to settle. This saves time and code because without it we would have to implement a dedication function to read the value from elsewhere.

Before the AB8500 External Regulator driver was Mainlined, it used to be conditionally compiled in using the CONFIG_REGULATOR_AB8500_EXT flag.
