[PATCH v6 06/13] dt-bindings: serial: snps-dw-apb-uart: add ambarella,cv75-uart

From: Long Zhao via B4 Relay <devnull+longzhao.ambarella.com@kernel.org>
Date: 2026-09-04 06:39:13
Also in: b4-sent, linux-arm-kernel, linux-clk, linux-gpio, linux-serial, lkml
Subsystem: open firmware and flattened device tree bindings, the rest, tty layer and serial drivers · Maintainers: Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds, Greg Kroah-Hartman, Jiri Slaby

From: Long Zhao <redacted>

Add the Ambarella CV75 compatible string to the Synopsys DW APB UART
binding. The block is Ambarella IP with a DW-like register map, so it
is described as a DW APB UART variant.
