+Bindings for Qualcomm Geni I3C master block
+===========================================
+
+Required properties:
+--------------------
+- compatible: shall be "qcom,geni-i3c"
+- clocks: shall reference the se clock
+- clock-names: shall contain clock name corresponding to the serial engine
+- interrupts: the interrupt line connected to this I3C master
+- reg: I3C master registers
+
+Optional properties:
+--------------------
+- se-clock-frequency: Source serial clock frequency to use
+- dfs-index: Dynamic frequency scaling table index to use
+
+Mandatory properties defined by the generic binding (see
+Documentation/devicetree/bindings/i3c/i3c.txt for more details):
+
+- #address-cells: shall be set to 3
+- #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-hz
+- i3c-scl-hz
+
+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 = "qcom,geni-i3c";
+ clocks = <&clock_gcc GCC_QUPV3_WRAP0_S0_CLK>;
+ clock-names = "se";
+ interrupts = <GIC_SPI 356 IRQ_TYPE_LEVEL_HIGH>;
+ reg = <0x0d040000 0x4000>;
+ #address-cells = <3>;
+ #size-cells = <0>;
+ i2c-scl-hz = <100000>;
+ };
