Date: Wed, 01 Aug 2012 09:15:11 +0800 From: Axel Lin <axel.lin@...il.com> To: Mark Brown <broonie@...nsource.wolfsonmicro.com> Cc: Liam Girdwood <lrg@...com>, linux-kernel@...r.kernel.org Subject: [PATCH] regulator: wm8400: Simplify set REGULATOR_MODE_IDLE mode in wm8400_dcdc_set_mode To set REGULATOR_MODE_IDLE mode, what we do is to clear DC1_ACTIVE and DC1_SLEEP bits, this can be done in one wm8400_set_bits() call.
