Subject: [PATCH v3 1/4] media: venus: Add codec data table
Date:   Tue, 25 Jun 2019 21:57:21 +0530
Message-Id: <1561480044-11834-2-git-send-email-amasule@codeaurora.org>
In-Reply-To: <1561480044-11834-1-git-send-email-amasule@codeaurora.org>
References: <1561480044-11834-1-git-send-email-amasule@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add vpp cycles for for different types of codec
It indicates the cycles required by video hardware
to process each macroblock. Initialize the codec
data with core resources.
