[PATCH v4 3/5] dt-bindings: serial: snps-dw-apb-uart: add Allwinner H616

[James Hilliard]

The H616 UART has 256-byte transmit and receive FIFOs, but its DesignWare
component parameter register does not report the FIFO depth. Its optional
register layout also differs from the generic DesignWare integration.

Add a specific compatible to identify this fixed configuration, retaining
snps,dw-apb-uart as a fallback.
