Subject: [PATCH 03/19] clk: samsung: exynos5433: Add clocks for CMU_PERIC domain
Date: Tue, 02 Dec 2014 17:49:40 +0900
Message-id: <1417510196-6714-4-git-send-email-cw00.choi@samsung.com>
In-reply-to: <1417510196-6714-1-git-send-email-cw00.choi@samsung.com>
References: <1417510196-6714-1-git-send-email-cw00.choi@samsung.com>
DLP-Filter: Pass
Sender: linux-kernel-owner@vger.kernel.org

This patch adds missing divider/gate clocks of CMU_PERIC domain
which includes I2S/PCM/SPDIF/PWM/SLIMBUS IPs. The SPI/I2S may use
external input clock which has 'ioclk_*' prefix.
