Subject: [PATCH v4 8/9] ARM: dts: Add the support for exynos busfreq on Exynos4412-based TRATS2 board
Date: Thu, 15 Jan 2015 10:50:56 +0900	[thread overview]
Message-ID: <1421286657-4720-9-git-send-email-cw00.choi@samsung.com> (raw)
In-Reply-To: <1421286657-4720-1-git-send-email-cw00.choi@samsung.com>

This patch adds the Exynos4412 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
MIF (Memory Interface) / INT (Internal) memory bus group.
