Subject: [PATCH v2 2/3] tty: serial: meson: Add a new compatible string for the G12A SoC
Date: Mon,  6 Mar 2023 20:42:22 +0100	[thread overview]
Message-ID: <20230306194223.1869814-3-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20230306194223.1869814-1-martin.blumenstingl@googlemail.com>

Amlogic Meson G12A (and later) SoCs also have the "divide XTAL by 2" bit
as the S4 UART controllers. Add a new compatible string for these SoCs
and enable the has_xtal_div2 flag for them.

Tested-by: Christian Hewitt <christianshewitt@gmail.com>
