Bindings for Synopsys DesignWare I3C master block

=================================================



Required properties:

--------------------

- compatible: shall be "snps,dw-i3c-master-1.00a"

- clocks: shall reference the core_clk

- interrupts: the interrupt line connected to this I3C master

- reg: Offset and length of I3C master registers



Mandatory properties defined by the generic binding (see

Documentation/devicetree/bindings/i3c/i3c.yaml 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.yaml 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.yaml for more details).



Example:



	i3c-master@2000 {

		compatible = "snps,dw-i3c-master-1.00a";

		#address-cells = <3>;

		#size-cells = <0>;

		reg = <0x02000 0x1000>;

		interrupts = <0>;

		clocks = <&i3cclk>;



		eeprom@57{

			compatible = "atmel,24c01";

			reg = <0x57 0x0 0x10>;

			pagesize = <0x8>;

		};

	};
