Pull ARM Soc updates, take 2, from Olof Johansson: "This is the second batch of SoC updates for the 3.8 merge window, containing parts that had dependencies on earlier branches such that we couldn't include them with the first branch. These are general updates for Samsung Exynos, Renesas/shmobile and a topic branch that adds SMP support to Altera's socfpga platform."

Pull ARM SoC device tree conversions and enablement from Olof Johansson: "Continued device tree conversion and enablement across a number of platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other smaller series as well. ux500 has seen continued conversion for platforms. Several platforms have seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra is adding data for new devices/drivers, and Exynos has a bunch of new bindings and devices added as well. So, pretty much the same progression in the right direction as the last few releases."

2012-04-04ARM: EXYNOS: Change System MMU platform device definitionsKyongHo Cho1-0/+90
Handling System MMUs with an identifier is not flexible to manage System MMU platform devices because of the following reasons: 1. A device driver which needs to handle System MMU must know the ID. 2. A System MMU may not present in some implementations of Exynos family. 3. Handling System MMU with IOMMU API does not require an ID. This patch is the result of removing ID of System MMUs. Instead, a device driver that needs to handle its System MMU must use IOMMU API while its descriptor of platform device is given. This patch also includes the following enhancements: - A System MMU device becomes a child if its power domain device. - clkdev Signed-off-by: KyongHo Cho <pullip.cho@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
