-* Renesas R-Car USB 2.0 clock selector
-
-This file provides information on what the device node for the R-Car USB 2.0
-clock selector.
-
-If you connect an external clock to the USB_EXTAL pin only, you should set
-the clock rate to "usb_extal" node only.
-If you connect an oscillator to both the USB_XTAL and USB_EXTAL, this module
-is not needed because this is default setting. (Of course, you can set the
-clock rates to both "usb_extal" and "usb_xtal" nodes.
-
-Case 1: An external clock connects to R-Car SoC
-	+----------+   +--- R-Car ---------------------+
-	|External  |---|USB_EXTAL ---> all usb channels|
-	|clock     |   |USB_XTAL                       |
-	+----------+   +-------------------------------+
-In this case, we need this driver with "usb_extal" clock.
-
-Case 2: An oscillator connects to R-Car SoC
-	+----------+   +--- R-Car ---------------------+
-	|Oscillator|---|USB_EXTAL -+-> all usb channels|
-	|          |---|USB_XTAL --+                   |
-	+----------+   +-------------------------------+
-In this case, we don't need this selector.
-
-Required properties:
-- compatible: "renesas,r8a7795-rcar-usb2-clock-sel" if the device is a part of
-	      an R8A7795 SoC.
-	      "renesas,r8a7796-rcar-usb2-clock-sel" if the device if a part of
-	      an R8A77960 SoC.
-	      "renesas,r8a77961-rcar-usb2-clock-sel" if the device if a part of
-	      an R8A77961 SoC.
-	      "renesas,rcar-gen3-usb2-clock-sel" for a generic R-Car Gen3
-	      compatible device.
-
-	      When compatible with the generic version, nodes must list the
-	      SoC-specific version corresponding to the platform first
-	      followed by the generic version.
-
-- reg: offset and length of the USB 2.0 clock selector register block.
-- clocks: A list of phandles and specifier pairs.
-- clock-names: Name of the clocks.
- - The functional clock of USB 2.0 host side must be "ehci_ohci"
- - The functional clock of HS-USB side must be "hs-usb-if"
- - The USB_EXTAL clock pin must be "usb_extal"
- - The USB_XTAL clock pin must be "usb_xtal"
-- #clock-cells: Must be 0
-- power-domains: A phandle and symbolic PM domain specifier.
-                 See power/renesas,rcar-sysc.yaml.
-- resets: A list of phandles and specifier pairs.
-- reset-names: Name of the resets.
- - The reset of USB 2.0 host side must be "ehci_ohci"
- - The reset of HS-USB side must be "hs-usb-if"
