Subject: [PATCH 3/5] OMAP4: PM: TWL6030: address 0V conversions
Date: Mon, 29 Aug 2011 11:15:19 -0700 [thread overview]
Message-ID: <1314641721-5172-4-git-send-email-khilman@ti.com> (raw)
In-Reply-To: <1314641721-5172-1-git-send-email-khilman@ti.com>
From: Nishanth Menon <nm@ti.com>
0V conversions should be mapped to 0 as it is meant to denote
off voltages.
