[PATCH v3 7/8] arm/tegra: implement support for tegra30
From: pdeschrijver@nvidia.com (Peter De Schrijver)
Date: 2011-11-07 14:20:45
Also in:
linux-tegra, lkml
Subsystem:
arm port, the rest · Maintainers:
Russell King, Linus Torvalds
Add support for tegra30 SoC. This includes a device tree compatible type for
this SoC ("nvidia,tegra30") and adds L2 cache initialization for this new SoC.
The clock framework is still missing, which prevents most drivers from working.
