Hm, why are you not CCing a bunch of people responsible for the DT
bindings maintenance that scripts/get_maintainer.pl should yield?

+* Renesas SH-Mobile Serial Communication Interface
+
+Required properties:
+
+ - compatible: one of the following types (scif, scifa, scifb, hscif).
+
+ - "renesas,scif-r8a7790" for R8A7790 (R-Car H2) SCIF compatible UART.
+ - "renesas,scifa-r8a7790" for R8A7790 (R-Car H2) SCIFA compatible UART.
+ - "renesas,scifb-r8a7790" for R8A7790 (R-Car H2) SCIFB compatible UART.
+ - "renesas,hscif-r8a7790" for R8A7790 (R-Car H2) HSCIF compatible UART.
+ - "renesas,scif-generic" for generic SCIF compatible UART.
+ - "renesas,scifa-generic" for generic SCIFA compatible UART.
+ - "renesas,scifb-generic" for generic SCIFB compatible UART.
+ - "renesas,hscif-generic" for generic HSCIF compatible UART.
+
+ When compatible with the generic version, nodes must also list the
+ SoC-specific version corresponding to the platform.
Which are not all specified here?
+
+ - reg: Base address and length of the memory resource used by the UART.
+
+ - interrupt-parent: Reference to the parent interrupt controller.
This is not a required property. It can be specified in the parent node.
+ - interrupts: Interrupt number.
s/number/specifier/
+
+ - clocks: Reference to the SCIx UART interface clock.
+ - clock-names: Should be "sci_ick".
+
+Note: Each enabled SCIx UART should have an alias correctly numbered in the
+"aliases" node.
+
+Example:
+ aliases {
+ serial0 = &scifa0;
+ };
+
+ scifa0: serial@e6c40000 {
+ compatible = "renesas,scifa-r8a7790", "renesas,scifa-generic";
+ reg = <0 0xe6c40000 0 64>;
+ interrupt-parent = <&gic>;
+ interrupts = <0 144 4>;
+ clocks = <&mstp2_clks 4>;
+ clock-names = "sci_ick";
+ };
