Subject: [PATCH v4 14/27] venus: helpers: add a helper function to set dynamic buffer mode
Date:   Wed, 27 Jun 2018 18:27:12 +0300
Message-Id: <20180627152725.9783-15-stanimir.varbanov@linaro.org>
In-Reply-To: <20180627152725.9783-1-stanimir.varbanov@linaro.org>
References: <20180627152725.9783-1-stanimir.varbanov@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Adds a new helper function to set dynamic buffer mode if it is
supported by current HFI version. The dynamic buffer mode is
set unconditionally for both decoder outputs.
