Subject: [PATCH V3 4/4] dts: Add cpufreq controller node for Exynos5440 SoC
Date: Thu, 7 Mar 2013 09:43:47 +0530 [thread overview]
Message-ID: <1362629627-10012-4-git-send-email-amit.daniel@samsung.com> (raw)
In-Reply-To: <1362629627-10012-1-git-send-email-amit.daniel@samsung.com>
Add cpufreq controller device node for Exynos5440 SoC for passing
parameters like controller base address, interrupt and cpufreq
table. This node is added outside cpu0 as this driver is now a platform
driver and a new device structure is needed.
Signed-off-by: Amit Daniel Kachhap <amit.daniel@samsung.com>
---
Changes in V3:
* Moved the DT node outside cpu0 node as the driver is now a platform
driver.
