From bae82bdfb1edb2d709bd4ba0bda1ed0bb474f5e1 Mon Sep 17 00:00:00 2001 From: MyungJoo Ham Date: Thu, 1 Dec 2011 16:00:38 +0900 Subject: [PATCH] ARM: EXYNOS: support Exynos4210-bus Devfreq driver on Nuri board Support varying voltages: - GPIODVS for Buck2 is removed. - Voltage ragne for Buck2 is widen. Support Buck2 regulator for Exynos4210-bus devfreq driver: - Added device name for buck2 regulator - Added exynos4210-busfreq platform device fro Nuri board.
