4 and sub-blocks in SoC. Most Exynos SoCs share the common architecture
5 for buses. Generally, each bus of Exynos SoC includes a source clock
7 of the bus in runtime. To monitor the usage of each bus in runtime,
9 is able to measure the current load of sub-blocks.
11 The Exynos SoC includes the various sub-blocks which have the each AXI bus.
12 The each AXI bus has the owned source clock but, has not the only owned
13 power line. The power line might be shared among one more sub-blocks.
14 So, we can divide into two type of device as the role of each sub-block.
15 There are two type of bus devices as following:
