When compatible with the generic version, nodes must list the
|
|
SoC-specific version corresponding to the platform first followed by the
|
|
generic version.
|
|
|

- reg: Base address and length of the I/O registers used by the UART.
|
|
- interrupts: Must contain an interrupt-specifier for the SCIx interrupt.
|
|
|
|
- clocks: Must contain a phandle and clock-specifier pair for each entry
|
|
in clock-names.
|
|
- clock-names: Must contain "sci_ick" for the SCIx UART interface clock.
|
|
|
|
Note: Each enabled SCIx UART should have an alias correctly numbered in the
|
|
"aliases" node.
|
|
|
|
Optional properties:
|
|
- dmas: Must contain a list of two references to DMA specifiers, one for
|
|
transmission, and one for reception.
|
|
- dma-names: Must contain a list of two DMA names, "tx" and "rx".
|
|
|
|
Example:
|
|
aliases {
|
|
serial0 = &scifa0;
|
|
};
|
|
