Subject: [PATCH v2 4/4] clk: tegra20: Bump SCLK clock rate to 216MHz
Date: Wed,  4 Oct 2017 02:02:41 +0300	[thread overview]
Message-ID: <9400057c3293e669a5f24fbfd3340f199e23d97f.1507070638.git.digetx@gmail.com> (raw)
In-Reply-To: <cover.1507070638.git.digetx@gmail.com>
In-Reply-To: <cover.1507070638.git.digetx@gmail.com>

AHB DMA is a running on 1/2 of SCLK rate, APB DMA on 1/4. Increasing SCLK
rate results in an increased DMA transfer rate.
