+Bindings for cadence I3C master block
+=====================================
+
+Required properties:
+--------------------
+- compatible: shall be "cdns,i3c-master"
+- clocks: shall reference the pclk and sysclk
+- clock-names: shall contain "pclk" and "sysclk"
+- interrupts: the interrupt line connected to this I3C master
+- reg: I3C master registers
+
+Mandatory properties defined by the generic binding (see
+Documentation/devicetree/bindings/i3c/i3c.txt for more details):
+
+- #address-cells: shall be set to 1
+- #size-cells: shall be set to 0
+
+Optional properties defined by the generic binding (see
+Documentation/devicetree/bindings/i3c/i3c.txt for more details):
+
+- i2c-scl-frequency
+- i3c-scl-frequency
+
+I3C device connected on the bus follow the generic description (see
+Documentation/devicetree/bindings/i3c/i3c.txt for more details).
+
+Example:
+
+ i3c-master@0d040000 {
+ compatible = "cdns,i3c-master";
+ clocks = <&coreclock>, <&i3csysclock>;
+ clock-names = "pclk", "sysclk";
+ interrupts = <3 0>;
+ reg = <0x0d040000 0x1000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ i2c-scl-frequency = <100000>;
+
+ nunchuk: nunchuk@52 {
+ compatible = "nintendo,nunchuk";
+ reg = <0x52>;
+ i3c-lvr = <0x10>;
+ };
+ };
