Subject: [PATCH v2 1/3] dt-bindings: serial: amlogic,meson-uart: Add compatible string for G12A
Date: Mon,  6 Mar 2023 20:42:21 +0100	[thread overview]
Message-ID: <20230306194223.1869814-2-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20230306194223.1869814-1-martin.blumenstingl@googlemail.com>

Amlogic G12A SoCs gained a new "divide XTAL by 2" bit. Everything else
(we know about) is identical to the UART IP on GX (GXBB/GXL/GXM) SoCs.
Add a new compatible string for this SoC so this new bit can be managed
accordingly while keeping "amlogic,meson-gx-uart" as fallback compatible
string.

Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com>

Changes from v1 -> v2:
- make meson-gx-uart a valid compatible string for meson-g12a-uart
