[PATCH v6 8/8] arm64: dts: allwinner: a523: describe the UART integration

[James Hilliard]

Identify the Allwinner UART integration on all eight CPUX controllers.
The specific compatible selects FIFO-depth discovery through FCC and the
Allwinner receive-trigger mapping. Each controller supplies its own depth,
so the same compatible covers the different FIFO capacities.

Retain snps,dw-apb-uart as a fallback. The common SoC description supplies
these UART nodes to the A527 and T527 boards as well.
