Subject: [PATCH] dt-bindings: serial: amlogic,meson-uart: Add compatible
 string for S6/S7/S7D

From: Xianwei Zhao <xianwei.zhao@...ogic.com>

Amlogic S6/S7/7D SoCs uses the same UART controller as S4 SoCs and G12A.
There is no need for an extra compatible line in the driver, but
add S6/S7/S7D compatible line for documentation.

It is just sent again separately since it goes via the tty tree
