Subject: [PATCH 15/15] ARM: dts: exynos: Remove MFC reserved buffers
Date: Tue, 14 Feb 2017 08:52:08 +0100	[thread overview]
Message-ID: <1487058728-16501-16-git-send-email-m.szyprowski@samsung.com> (raw)
In-Reply-To: <1487058728-16501-1-git-send-email-m.szyprowski@samsung.com>

During my research I found that some of the requirements for the memory
buffers for MFC v6+ devices were blindly copied from the previous (v5)
version and simply turned out to be excessive. The relaxed requirements
are applied by the recent patches to the MFC driver and the driver is
now fully functional even without the reserved memory blocks for all
v6+ variants. This patch removes those reserved memory nodes from all
boards having MFC v6+ hardware block.
