From f7b1a8dc1c1ca30d6a9ceb1f23f0e9847668600b Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 21 Mar 2014 16:15:20 +0800 Subject: regulator: s2mpa01: Don't check enable_shift before setting enable ramp rate Current code misses updating the register when enable_shift is 0. e.g. S2MPA01_BUCK4_RAMP_EN_SHIFT is 0.
