-Renesas RZ/A2 combined Pin and GPIO controller
-
-The Renesas SoCs of the RZ/A2 series feature a combined Pin and GPIO controller.
-Pin multiplexing and GPIO configuration is performed on a per-pin basis.
-Each port features up to 8 pins, each of them configurable for GPIO
-function (port mode) or in alternate function mode.
-Up to 8 different alternate function modes exist for each single pin.
-
-Pin controller node
--------------------
-
-Required properties:
-  - compatible: shall be:
-    - "renesas,r7s9210-pinctrl": for RZ/A2M
-  - reg
-    Address base and length of the memory area where the pin controller
-    hardware is mapped to.
-  - gpio-controller
-    This pin controller also controls pins as GPIO
-  - #gpio-cells
-    Must be 2
-  - gpio-ranges
-    Expresses the total number of GPIO ports/pins in this SoC
-
-Example: Pin controller node for RZ/A2M SoC (r7s9210)
-
-	pinctrl: pin-controller@fcffe000 {
-		compatible = "renesas,r7s9210-pinctrl";
-		reg = <0xfcffe000 0x1000>;
-
-		gpio-controller;
-		#gpio-cells = <2>;
-		gpio-ranges = <&pinctrl 0 0 176>;
-	};
-
-Sub-nodes
----------
-
-The child nodes of the pin controller designate pins to be used for
-specific peripheral functions or as GPIO.
-
-- Pin multiplexing sub-nodes:
-  A pin multiplexing sub-node describes how to configure a set of
-  (or a single) pin in some desired alternate function mode.
-  The values for the pinmux properties are a combination of port name, pin
-  number and the desired function index. Use the RZA2_PINMUX macro located
-  in include/dt-bindings/pinctrl/r7s9210-pinctrl.h to easily define these.
-  For assigning GPIO pins, use the macro RZA2_PIN also in r7s9210-pinctrl.h
-  to express the desired port pin.
-
-  Required properties:
-    - pinmux:
-      integer array representing pin number and pin multiplexing configuration.
-      When a pin has to be configured in alternate function mode, use this
-      property to identify the pin by its global index, and provide its
-      alternate function configuration number along with it.
-      When multiple pins are required to be configured as part of the same
-      alternate function they shall be specified as members of the same
-      argument list of a single "pinmux" property.
-      Helper macros to ease assembling the pin index from its position
-      (port where it sits on and pin number) and alternate function identifier
-      are provided by the pin controller header file at:
-      <dt-bindings/pinctrl/r7s9210-pinctrl.h>
-      Integers values in "pinmux" argument list are assembled as:
-      ((PORT * 8 + PIN) | MUX_FUNC << 16)
-
-  Example: Board specific pins configuration
-
-	&pinctrl {
-		/* Serial Console */
-		scif4_pins: serial4 {
-			pinmux = <RZA2_PINMUX(PORT9, 0, 4)>,	/* TxD4 */
-				 <RZA2_PINMUX(PORT9, 1, 4)>;	/* RxD4 */
-		};
-	};
-
-  Example: Assigning a GPIO:
-
-	leds {
-		status = "okay";
-		compatible = "gpio-leds";
-
-		led0 {
-			/* P6_0 */
-			gpios = <&pinctrl RZA2_PIN(PORT6, 0) GPIO_ACTIVE_HIGH>;
-		};
-	};

This paragraph formatting looks odd, but I'm not sure it's intentional 
or not :-) In either case with or without this changed,

If you do want the formatting here maintained, you need a '|'.
