Subject: [PATCH v2 1/3] regulator: DT: Add DT property for operation mode configuration
Date: Mon, 23 May 2016 15:13:29 +0800	[thread overview]
Message-ID: <1463987611-32139-2-git-send-email-henryc.chen@mediatek.com> (raw)
In-Reply-To: <1463987611-32139-1-git-send-email-henryc.chen@mediatek.com>

Some regulators support their operating mode to be changed by consumers for
module specific purpose. Add a DT property to support this.
