Subject: [PATCH 03/12] clk: tegra: Add TEGRA_PERIPH_NO_DIV flag
Date: Wed, 18 Sep 2013 17:40:55 +0300	[thread overview]
Message-ID: <1379515331-19427-4-git-send-email-pdeschrijver@nvidia.com> (raw)
In-Reply-To: <1379515331-19427-1-git-send-email-pdeschrijver@nvidia.com>

This flag indicates the peripheral clock does not have a divider. It will
simply the initialization tables and avoids some very similar code.
