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.
