Document the "axiado,ax3005-uart" SoC-specific compatible with "cdns,uart-r1p12" as its fallback. This preserves identification of the AX3005 integration while allowing the controller to use the existing Cadence r1p12 UART support. Acked-by: Krzysztof Kozlowski Signed-off-by: Swark Yang Acked-by: Michal Simek --- This UART binding was previously submitted as patch 5/8 of the AX3005 v3 multi-subsystem series. Following maintainer feedback, the binding updates are now submitted separately to their respective subsystem maintainers, as there are no cross-subsystem dependencies requiring them to be submitted together. This submission contains only the AX3005 UART binding. The corresponding UART controller nodes remain in the separate AX3005 arm64 Devicetree series. Changes in v4: - Submit the UART binding separately from the previous multi-subsystem AX3005 series. - Expand the commit message to explain compatibility with the Cadence r1p12 UART programming interface. - Add Krzysztof's Acked-by tag. - No binding schema changes.
