32 | When compatible with the generic version, nodes must list the | |
33 | SoC-specific version corresponding to the platform first followed by the | |
34 | generic version. | |
35 | ||
36 | - reg: Base address and length of the I/O registers used by the UART. | |
37 | - interrupts: Must contain an interrupt-specifier for the SCIx interrupt. | |
38 | ||
39 | - clocks: Must contain a phandle and clock-specifier pair for each entry | |
40 | in clock-names. | |
41 | - clock-names: Must contain "sci_ick" for the SCIx UART interface clock. | |
42 | ||
43 | Note: Each enabled SCIx UART should have an alias correctly numbered in the | |
44 | "aliases" node. | |
45 | ||
46 | Example: | |
47 | aliases { | |
48 | serial0 = &scifa0; | |
49 | }; | |
50 | ||
51 | scifa0: serial@e6c40000 { | |
