Subject: [PATCH v8 06/26] memory: tegra30: Add FIFO sizes to memory clients
Date:   Wed, 11 Nov 2020 04:14:36 +0300
Message-Id: <20201111011456.7875-7-digetx@gmail.com>
In-Reply-To: <20201111011456.7875-1-digetx@gmail.com>
References: <20201111011456.7875-1-digetx@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The latency allowness is calculated based on buffering capabilities of
memory clients. Add FIFO sizes to the Tegra30 memory clients.
