-Binding for the axi-clkgen clock generator
-
-This binding uses the common clock binding[1].
-
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible : shall be "adi,axi-clkgen-1.00.a" or "adi,axi-clkgen-2.00.a".
-- #clock-cells : from common clock binding; Should always be set to 0.
-- reg : Address and length of the axi-clkgen register set.
-- clocks : Phandle and clock specifier for the parent clock(s). This must
- either reference one clock if only the first clock input is connected or two
- if both clock inputs are connected. For the later case the clock connected
- to the first input must be specified first.
-
-Optional properties:
-- clock-output-names : From common clock binding.
-
-Example:
- clock@ff000000 {
- compatible = "adi,axi-clkgen";
- #clock-cells = <0>;
- reg = <0xff000000 0x1000>;

-* 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"
-
-Example (R-Car H3):
-
- usb2_clksel: clock-controller@e6590630 {
- compatible = "renesas,r8a7795-rcar-usb2-clock-sel",
- "renesas,rcar-gen3-usb2-clock-sel";

- <&usb_extal>, <&usb_xtal>;
- clock-names = "ehci_ohci", "hs-usb-if", "usb_extal", "usb_xtal";
- #clock-cells = <0>;
- power-domains = <&sysc R8A7795_PD_ALWAYS_ON>;
- resets = <&cpg 703>, <&cpg 704>;

+description:
+ On the FU740 family of SoCs, most system-wide clock and reset integration
+ is via the PRCI IP block.
+ The clock consumer should specify the desired clock via the clock ID
+ macros defined in include/dt-bindings/clock/sifive-fu740-prci.h.
+ These macros begin with PRCI_CLK_.
+
+ The hfclk and rtcclk nodes are required, and represent physical
+ crystals or resonators located on the PCB. These nodes should be present
+ underneath /, rather than /soc.
