Date: Fri, 17 Feb 2012 18:56:11 +0530 From: Laxman Dewangan <ldewangan@...dia.com> To: broonie@...nsource.wolfsonmicro.com, lrg@...com, linux-kernel@...r.kernel.org Cc: linux-tegra@...r.kernel.org, ldewangan@...dia.com Subject: [PATCH V1] regulator: tps65910: Correct VIO voltage configuration The VIO regulator register specify the voltage configuration on bit3:2 of its register. And hence only these bits should be modified when setting voltage and used when reading voltage from register setting.
