7 title: Renesas R-Car USB 2.0 clock selector
10   - Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>
13   If you connect an external clock to the USB_EXTAL pin only, you should set
15   If you connect an oscillator to both the USB_XTAL and USB_EXTAL, this module
19   Case 1: An external clock connects to R-Car SoC
20     +----------+   +--- R-Car ---------------------+
21     |External  |---|USB_EXTAL ---> all usb channels|

27   Case 2: An oscillator connects to R-Car SoC
28     +----------+   +--- R-Car ---------------------+
