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
14 the clock rate to "usb_extal" node only.
17 clock rates to both "usb_extal" and "usb_xtal" nodes.
19 Case 1: An external clock connects to R-Car SoC
