Subject: [PATCH v3 1/3] 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.
Signed-off-by: Martin Blumenstingl <martin.blumenstingl@...glemail.com>

Changes from v1 -> v2:
- make meson-gx-uart a valid compatible string for meson-g12a-uart
Changes from v2 -> v3:
- don't add extra oneOf as all of the entries are enclosed in oneOf
already
- don't allow amlogic,meson-g12a-uart as standalone compatible string
(which slipped through in v2 due to all of the formatting changes
that the extra oneOf required)
