This patch is for new lp8755 regulator dirver and several unsed variables were deleted and then test was done. LP8755 : The LP8755 is a high performance power management unit.It contains six step-down DC-DC converters which can can be filexibly bundled together in multiphase converters as required by application. www.ti.com Signed-off-by: Daniel Jeong <gshark.jeong@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
