Subject: [PATCH 2/3] dt-bindings: serial: snps-dw-apb-uart: Add Allwinner A733
Date: Mon, 5 Oct 2026 14:25:37 -0300 [thread overview]
Message-ID: <20261005172538.398522-3-vinicius.eduardo.pedrosa@gmail.com> (raw)
In-Reply-To: <20261005172538.398522-1-vinicius.eduardo.pedrosa@gmail.com>
The Allwinner A733 UART is a DesignWare APB UART with two SoC-specific
differences. Its baud clock is the bus clock gate, which can't change
rate, and offset 0xc0 holds an RS485 control register instead of DLF.
Add a SoC-specific compatible, with "snps,dw-apb-uart" as the fallback.
