This patch adds PPMU (Performance Profiling Monitoring Unit) dt node Exynos5260 SoC. Exynos5260 SoC has following PPMU IPs: - PPMU_DREX0_S0 0x10c60000 - PPMU_DREX0_S1 0x10c70000 - PPMU_DREX1_S0 0x10c80000 - PPMU_DREX1_S1 0x10c90000 - PPMU_EAGLE 0x10cc0000 - PPMU_KFC 0x10cd0000 - PPMU_MFC 0x11040000 - PPMU_G3D 0x11880000 - PPMU_FSYS 0x12220000 - PPMU_ISP 0x13370000 - PPMU_FICM 0x13cb0000 - PPMU_GSCL 0x13e60000 - PPMU_MSCL 0x13ee0000 - PPMU_FIMD0X 0x145b0000 - PPMU_FIMD1X 0x145c0000 The drivers/devfreq/exynos/exynos5_bus.c supports the memory bus frequency/ voltage scaling of Exynos5260 SoC with DEVFREQ framework.
