Subject: [PATCH v2 2/3] dt-bindings: serial: amlogic,meson-uart: Add compatible string for A9
Date: Sat, 28 Feb 2026 07:56:15 +0000 [thread overview]
Message-ID: <20260228-a9-baisc-dts-v2-2-47489d5cc1a8@amlogic.com> (raw)
In-Reply-To: <20260228-a9-baisc-dts-v2-0-47489d5cc1a8@amlogic.com>
From: Xianwei Zhao <xianwei.zhao@amlogic.com>
Amlogic A9 SoCs uses the same UART controller as S4 SoCs.
There is no need for an extra compatible line in the driver,
but add A9 compatible line for documentation.
