Subject: [PATCH 1/2] regulator: twl6030: do not write to _GRP for regulator enable
Date: Fri, 20 May 2011 19:03:51 +0530	[thread overview]
Message-ID: <1305898432-14939-2-git-send-email-balajitk@ti.com> (raw)
In-Reply-To: <1305898432-14939-1-git-send-email-balajitk@ti.com>

TWL6030: regulator is enabled via VREG_STATE
TWL4030: regulator is enabled via VREG_GRP
Since there is nothing common, split twlreg_enable similar to other regulator_ops
