Subject: [PATCH v2 04/22] drm/exynos: rotator: convert to common clock framework
Date: Mon, 30 Nov 2015 14:53:19 +0100	[thread overview]
Message-ID: <1448891617-18830-5-git-send-email-m.szyprowski@samsung.com> (raw)
In-Reply-To: <1448891617-18830-1-git-send-email-m.szyprowski@samsung.com>

This driver was not used after introduction of common clock framework.
This patch adds missing prepare/unprepare calls and allows to use it
again with current kernel code.
