-
- When compatible with the generic version, nodes must list the
- SoC-specific version corresponding to the platform first, followed by the
- family-specific and/or generic versions.
-
- - reg: Base address and length of the I/O registers used by the UART.
- - interrupts: Must contain one or more interrupt-specifiers for the SCIx.
- If a single interrupt is expressed, then all events are
- multiplexed into this single interrupt.
-
- If multiple interrupts are provided by the hardware, the order
- in which the interrupts are listed must match order below. Note
- that some HW interrupt events may be muxed together resulting
- in duplicate entries.
- The interrupt order is as follows:
- 1. Error (ERI)
- 2. Receive buffer full (RXI)
- 3. Transmit buffer empty (TXI)
- 4. Break (BRI)
- 5. Data Ready (DRI)
- 6. Transmit End (TEI)
-
- - clocks: Must contain a phandle and clock-specifier pair for each entry
- in clock-names.
- - clock-names: Must contain "fck" for the SCIx UART functional clock.
- Apart from the divided functional clock, there may be other possible
- sources for the sampling clock, depending on SCIx variant.
- On (H)SCI(F) and some SCIFA, an additional clock may be specified:
- - "hsck" for the optional external clock input (on HSCIF),
- - "sck" for the optional external clock input (on other variants).
- On UARTs equipped with a Baud Rate Generator for External Clock (BRG)
- (some SCIF and HSCIF), additional clocks may be specified:
- - "brg_int" for the optional internal clock source for the frequency
- divider (typically the (AXI or SHwy) bus clock),
- - "scif_clk" for the optional external clock source for the frequency
- divider (SCIF_CLK).
-
-Note: Each enabled SCIx UART may have an optional "serialN" alias 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".
- - {cts,dsr,dcd,rng,rts,dtr}-gpios: Specify GPIOs for modem lines, cfr. the
- generic serial DT bindings in serial.txt.
- - uart-has-rtscts: Indicates dedicated lines for RTS/CTS hardware flow
- control, cfr. the generic serial DT bindings in serial.txt.
-
-Example:
- aliases {
- serial0 = &scifa0;
- };
-
- scifa0: serial@e6c40000 {
- compatible = "renesas,scifa-r8a7790",
- "renesas,rcar-gen2-scifa", "renesas,scifa";
- reg = <0 0xe6c40000 0 64>;
- interrupt-parent = <&gic>;
- interrupts = <0 144 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&mstp2_clks R8A7790_CLK_SCIFA0>;
- clock-names = "fck";
- dmas = <&dmac0 0x21>, <&dmac0 0x22>;
- dma-names = "tx", "rx";
- };
