dt-bindings: i3c: snps: Add Altera SoCFPGA compatible

2025-11-08T21:50:46Z

Add the "altr,agilex5-dw-i3c-master" compatible string to the Synopsys DesignWare I3C master binding. This allow Agilex5 to use the generic DW I3C master controller while applying any required platform-specific quirks.

dt-bindings: i3c: renesas,i3c: Add RZ/V2H(P) and RZ/V2N support

2025-09-16T15:06:43Z

Add device tree binding support for the I3C Bus Interface on Renesas RZ/V2H(P) and RZ/V2N SoCs. The I3C IP on these SoCs is identical to that found on the RZ/G3E SoC. Add new compatible strings "renesas,r9a09g056-i3c" for RZ/V2N and "renesas,r9a09g057-i3c" for RZ/V2H(P). Both variants use "renesas,r9a09g047-i3c" as a fallback compatible to indicate hardware compatibility with the RZ/G3E implementation. Update the title to be more generic as it now covers multiple SoC families beyond just RZ/G3S and RZ/G3E.

dt-bindings: i3c: Add adi-i3c-master

2025-09-16T15:06:43Z

Add bindings doc for ADI I3C Controller IP core, a FPGA synthesizable IP core that implements the MIPI I3C Basic controller specification. The IP Core is versioned following Semantic Versioning 2.0.0 and ADI's open-source HDL guidelines for devicetree bindings and drivers.

dt-bindings: i3c: silvaco,i3c-master: add i.MX94 and i.MX95 I3C

2025-05-24T20:45:36Z

Add compatible string "nxp,imx94-i3c" and "nxp,imx95-i3c" for the i.MX94 chip and i.MX95 chip. Backward is compatible with "silvaco,i3c-master-v1". Also i.MX94 and i.MX95 I3C only need two clocks and Legacy I3C needs three clocks. So add restrictions for clock and clock-names properties for different Socs.
