87 When compatible with the generic version, nodes must list the
88 SoC-specific version corresponding to the platform first, followed by the
89 family-specific and/or generic versions.
91 - reg: Base address and length of the I/O registers used by the UART.
92 - interrupts: Must contain one or more interrupt-specifiers for the SCIx.
93 If a single interrupt is expressed, then all events are
94 multiplexed into this single interrupt.
96 If multiple interrupts are provided by the hardware, the order
97 in which the interrupts are listed must match order below. Note
98 that some HW interrupt events may be muxed together resulting
100 The interrupt order is as follows:
102 2. Receive buffer full (RXI)
103 3. Transmit buffer empty (TXI)
106 6. Transmit End (TEI)
108 - clocks: Must contain a phandle and clock-specifier pair for each entry
110 - clock-names: Must contain "fck" for the SCIx UART functional clock.
111 Apart from the divided functional clock, there may be other possible
112 sources for the sampling clock, depending on SCIx variant.
113 On (H)SCI(F) and some SCIFA, an additional clock may be specified:
114 - "hsck" for the optional external clock input (on HSCIF),
115 - "sck" for the optional external clock input (on other variants).
116 On UARTs equipped with a Baud Rate Generator for External Clock (BRG)
117 (some SCIF and HSCIF), additional clocks may be specified:
118 - "brg_int" for the optional internal clock source for the frequency
119 divider (typically the (AXI or SHwy) bus clock),
120 - "scif_clk" for the optional external clock source for the frequency
123 Note: Each enabled SCIx UART may have an optional "serialN" alias in the
127 - dmas: Must contain a list of two references to DMA specifiers, one for
128 transmission, and one for reception.
129 - dma-names: Must contain a list of two DMA names, "tx" and "rx".
130 - {cts,dsr,dcd,rng,rts,dtr}-gpios: Specify GPIOs for modem lines, cfr. the
131 generic serial DT bindings in serial.txt.
132 - uart-has-rtscts: Indicates dedicated lines for RTS/CTS hardware flow
133 control, cfr. the generic serial DT bindings in serial.txt.
