Wed Jan 11 14:55:19 CET 2012
Samsung's ARM Cortex-A15 based SoCs are known as Exynos5 series of
SoCs. This patch adds the support for Exynos5.
Signed-off-by: Chander Kashyap <chander.kashyap at linaro.org>
---
Changes for v2:
- This patch was part of "EXYNOS: Add SMDK5250 board support"
- Now it is seprated as SoC support.
Changes for v333:
- Populated complete exynos5 gpio structures
