Subject: [RFC v2 6/7] ARM: dts: exynos4x12: add suspend OPP for DMC and leftbus
Date: Mon, 19 Dec 2016 03:16:26 +0100 [thread overview]
Message-ID: <1482113787-28422-7-git-send-email-tjakobi@math.uni-bielefeld.de> (raw)
In-Reply-To: <1482113787-28422-1-git-send-email-tjakobi@math.uni-bielefeld.de>
Both DMC and leftbus adjust regulator voltages (MIF and INT
respectively), which have to be in a safe range to allow the
BL0 to operate correctly.
