+* Renesas R9A06G032 SYSCTRL
+
+Required Properties:
+
+ - compatible: Must be:
+ - "renesas,r9a06g032-sysctrl"
+ - reg: Base address and length of the SYSCTRL IO block.
+ - #clock-cells: Must be 1
+
+Examples
+--------
+
+ - SYSCTRL node:
+
+ sysctrl: system-controller@4000c000 {
+ compatible = "renesas,r9a06g032-sysctrl";
+ reg = <0x4000c000 0x1000>;
+ #clock-cells = <1>;
+ };
+
+ - Other nodes can use the clocks provided by SYSCTRL as in:
+
+ #include <dt-bindings/clock/r9a06g032-sysctrl.h>
+ uart0: serial@40060000 {
+ compatible = "snps,dw-apb-uart";
+ reg = <0x40060000 0x400>;
+ interrupts = <GIC_SPI 6 IRQ_TYPE_LEVEL_HIGH>;
+ reg-shift = <2>;
+ reg-io-width = <4>;
+ clocks = <&sysctrl R9A06G032_CLK_UART0>;
+ clock-names = "baudclk";
+ };
