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 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) .../devicetree/bindings/serial/amlogic,meson-uart.yaml | 9 +++++++++ 1 file changed, 9 insertions(+)
