This block consists two functional blocks (XBar assist and VBus assist) and one system access interface using APB. The primary functionality of XBar assist is: - switching lane for flip - moving unused lanes into lower power states. This info can be get from: i.MX95 RM Chapter 163.3.8 Type-C assist (TCA) block. This will add support for TCA block to achieve lane switching and tca lower power functionality.
