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>;
};
