Subject: [v3 2/9] HACK: ARM: tegra: Use CLK_IGNORE_UNUSED for Tegra 114 SoC
Date: Tue, 15 Jan 2013 10:13:11 +0200	[thread overview]
Message-ID: <1358237598-32413-3-git-send-email-hdoyu@nvidia.com> (raw)
In-Reply-To: <1358237598-32413-1-git-send-email-hdoyu-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Use CLK_IGNORE_UNUSED for the Tegra 114 SoC to ensure
clk_disable_unused() is not called. Otherwise the system will die,
because the usecount of the clocks is incorrect. This patch will be
reverted once the Tegra 114 clocks are implemented.

Signed-off-by: Hiroshi Doyu <hdoyu-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

NOTE: Will be updated once the latest ccf is merged.
