4Required properties:
5--------------------
6- compatible: shall be "snps,dw-i3c-master-1.00a"
7- clocks: shall reference the core_clk
8- interrupts: the interrupt line connected to this I3C master

10
11Mandatory properties defined by the generic binding (see
12Documentation/devicetree/bindings/i3c/i3c.txt for more details):
13
14- #address-cells: shall be set to 3
15- #size-cells: shall be set to 0
