-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.yaml 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.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@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-hz = <100000>;
-
- nunchuk: nunchuk@52 {
- compatible = "nintendo,nunchuk";
- reg = <0x52 0x0 0x10>;
- };
- };
