Hi All, I have couple of doubts regarding platform bus. 1) In arm architecture, which bus we call it as platform bus? 2) Why platform bus is called as virtual bus?
The platform bus is a catch-all for devices that don't have a real bus type, like PCI, I2C, SPI, etc., associated with it. It is a construct within Linux, and unlike PCI which is a real hardware bus, hence being called a "virtual" bus. ChenYu
