From add5dfe87abe962cf9884193d9467f23d898fb8b Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Tue, 7 Mar 2023 23:26:49 +0100 Subject: [PATCH] dt-bindings: serial: amlogic,meson-uart: Add compatible string for G12A 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.
