This patch add PPMU (Platform Performance Monitoring Unit) dt node
to estimate the utilization of each IP in Exynos SoC throught DEVFREQ Event
subsystem.
This patch adds following PPMU dt nodes:
- PPMU_DMC0 0x106a0000
- PPMU_DMC1 0x106b0000
- PPMU_RIGHTBUS 0x112A0000
- PPMU_LEFTBUS 0x116A0000
- PPMU_CAMIF 0x11AC0000
- PPMU_LCD0 0x11E40000
- PPMU_FSYS 0x12630000
- PPMU_3D 0x13220000
- PPMU_MFC 0x13660000
- PPMU_CPU 0x106c0000
