Subject: [PATCH v7 01/12] clk: tegra: provide dummy cpu car ops
Date: Fri, 15 Feb 2013 14:36:31 +0200	[thread overview]
Message-ID: <1360931849-7090-2-git-send-email-pdeschrijver@nvidia.com> (raw)
In-Reply-To: <1360931849-7090-1-git-send-email-pdeschrijver@nvidia.com>

tegra_boot_secondary() relies on some of the car ops. This means having an
uninitialized tegra_cpu_car_ops will lead to an early boot panic.
Providing a dummy struct avoids this and makes adding Tegra114 clock support
in a bisectable way a lot easier.
