Subject: [RFC PATCH 4/4] ARM: dts: Add memory bus node for Exynos3250-based Rinato board
Date: Tue, 23 Dec 2014 20:44:37 +0900	[thread overview]
Message-ID: <1419335077-31020-5-git-send-email-cw00.choi@samsung.com> (raw)
In-Reply-To: <1419335077-31020-1-git-send-email-cw00.choi@samsung.com>

This patch adds the exynos memory-bus node which includes the regulator and
devfreq-event phandle. The devfreq-event phandle is used for the governor
of devfreq device and provide the current usage state of DMC/Internal
memory bus group.
