regulator: ab8500: Add missing enable_time settings
Base on the data provide by Bengt Jönsson, add below enable_time settings: Worst case enable time from data sheet: Vana: enable time = 140 us Vaux1/2: enable time = 200 us Vaux3: enable time = 450 us Vintcore: enable time = 750 us Vamic1/2: enable time = 500 us Vdmic: enable time = 420 us VTVout: enable time = 500 us Vaudio: enable time = 140 us Vusb: enable time = 150 us This discussion thread is available at: https://lkml.org/lkml/2013/3/26/795 Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Bengt Jonsson <bengt.g.jonsson@stericsson.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
