This document lists a set of generic properties for describing UARTs in a
|
|
device tree. Whether these properties apply to a particular device depends
|
|
on the DT bindings for the actual device.
|
|
|
|
Each enabled UART may have an optional "serialN" alias in the "aliases" node,
|
|
where N is the port number (non-negative decimal integer) as printed on the
|
|
label next to the physical port.

The presence of this property indicates that the UART has dedicated lines
|
|
for RTS/CTS hardware flow control, and that they are available for use
|
|
(wired and enabled by pinmux configuration). This depends on both the
|
|
UART hardware and the board wiring.
