Subject: [PATCH] regulator: mt6311: Modify the maximum voltage of buck.
Date: Mon, 3 Aug 2015 22:15:51 +0800 [thread overview]
Message-ID: <1438611351-4245-1-git-send-email-henryc.chen@mediatek.com> (raw)
The maximum voltage of buck should be 1.39375V.
1.39375V = 0.6V + 0.00625V * 127, 127 is the max_sel of linear range.
