13 A Simple Power-Managed Bus is a transparent bus that doesn't need a real

17 of a functional clock. Hence, the bus controller's PM domain and/or

12 The Renesas Bus State Controller (BSC, sometimes called "LBSC within Bus
13 Bridge", or "External Bus Interface") can be found in several Renesas ARM
14 SoCs. It provides an external bus for connecting multiple external
