Message-ID: <1565703113-31479-2-git-send-email-andrew-sh.cheng@mediatek.com> (raw)
In-Reply-To: <1565703113-31479-1-git-send-email-andrew-sh.cheng-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>
From: "Andrew-sh.Cheng" <andrew-sh.cheng-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>
For new mediatek chip mt8183,
cci and little cluster share the same buck,
so need to modify the attribute of regulator from exclusive to optional
