Subject: [PATCH 04/14] omap: iovmm: remove cache flush operation
Date: Thu, 12 Nov 2009 16:08:01 -0800 [thread overview]
Message-ID: <20091113000801.9034.78473.stgit@localhost> (raw)
In-Reply-To: <20091113000444.9034.41293.stgit@localhost>
From: Hiroshi DOYU <Hiroshi.DOYU@nokia.com>
Cache flush operation is handled in the upper client layer and iovmm
modules doesn't have to care about it. This patch will improve some
performance with current camera isp driver.
