33    When compatible with the generic version, nodes must list the
34    SoC-specific version corresponding to the platform first followed by the
35    generic version.
36
37  - reg: Base address and length of the I/O registers used by the UART.
38  - interrupts: Must contain an interrupt-specifier for the SCIx interrupt.
39
40  - clocks: Must contain a phandle and clock-specifier pair for each entry
41    in clock-names.
42  - clock-names: Must contain "sci_ick" for the SCIx UART interface clock.
43
44Note: Each enabled SCIx UART should have an alias correctly numbered in the
45"aliases" node.
