Subject: [PATCH 2/2] regulator: twl6030: do not write to _GRP for regulator disable
Date: Fri, 20 May 2011 19:03:52 +0530 [thread overview]
Message-ID: <1305898432-14939-3-git-send-email-balajitk@ti.com> (raw)
In-Reply-To: <1305898432-14939-1-git-send-email-balajitk@ti.com>
TWL6030: regulator is disabled via VREG_STATE
TWL4030: regulator is disabled via VREG_GRP
Since there is nothing common, split twlreg_enable similar to other regulator_ops
