dt-bindings: serial: renesas,scif: Document RZ/G3L SoC

2026-01-23T16:24:51+00:00

Add SCIF binding documentation for Renesas RZ/G3L SoC. SCIF block on the RZ/G3L is identical to one found on the RZ/G3S SoC.

dt-bindings: serial: google,goldfish-tty: Convert to DT schema

2026-01-16T13:25:57+00:00

Convert the Google Goldfish TTY binding to DT schema format. Move the file to the serial directory to match the subsystem. Update the example node name to 'serial' to comply with generic node naming standards.

dt-bindings: serial: renesas,rsci: Document RZ/V2H(P) and RZ/V2N SoCs

2026-01-16T13:25:01+00:00

Document the serial communication interface (RSCI) used on the Renesas RZ/V2H(P) (R9A09G057) and RZ/V2N (R9A09G056) SoCs. These SoCs integrate the same RSCI IP block as the RZ/G3E (R9A09G047), so the RZ/G3E compatible is used as a fallback for both.

dt-bindings: serial: 8250: add SpacemiT K3 UART compatible

2025-12-23T10:52:27+00:00

The SpacemiT K3 UART controller is compatible with the Intel XScale UART. Add K3 UART binding and allow describing it with a fixed clock-frequency for now. The clocks and clock-names properties will be made mandatory in a future patch, once the K3 clock driver and device tree are merged.

dt-bindings: serial: renesas,rsci: Document RZ/G3E support

2025-12-17T14:07:06+00:00

Add documentation for the serial communication interface (RSCI) found on the Renesas RZ/G3E (R9A09G047) SoC. The RSCI IP on this SoC is identical to that on the RZ/T2H (R9A09G077) SoC, but it has a 32-stage FIFO compared to 16 on RZ/T2H. It supports both FIFO and non-FIFO mode operation. RZ/G3E has 6 clocks(5 module clocks + 1 external clock) compared to 3 clocks (2 module clocks + 1 external clock) on RZ/T2H, and it has multiple resets. It has 6 interrupts compared to 4 on RZ/T2H.
