1* Renesas SH-Mobile Serial Communication Interface
2
3Required properties:
4
5 - compatible: Must contain one of the following:
6
7 - "renesas,scif-r8a7790" for R8A7790 (R-Car H2) SCIF compatible UART.
8 - "renesas,scifa-r8a7790" for R8A7790 (R-Car H2) SCIFA compatible UART.
9 - "renesas,scifb-r8a7790" for R8A7790 (R-Car H2) SCIFB compatible UART.
10 - "renesas,hscif-r8a7790" for R8A7790 (R-Car H2) HSCIF compatible UART.
11 - "renesas,scif-r8a7791" for R8A7791 (R-Car M2) SCIF compatible UART.
12 - "renesas,scifa-r8a7791" for R8A7791 (R-Car M2) SCIFA compatible UART.
13 - "renesas,scifb-r8a7791" for R8A7791 (R-Car M2) SCIFB compatible UART.
14 - "renesas,hscif-r8a7791" for R8A7791 (R-Car M2) HSCIF compatible UART.
15 - "renesas,scif" for generic SCIF compatible UART.
16 - "renesas,scifa" for generic SCIFA compatible UART.
17 - "renesas,scifb" for generic SCIFB compatible UART.
18 - "renesas,hscif" for generic HSCIF compatible UART.
19
20 When compatible with the generic version, nodes must list the
21 SoC-specific version corresponding to the platform first followed by the
22 generic version.
23
24 - reg: Base address and length of the I/O registers used by the UART.
25 - interrupts: Must contain an interrupt-specifier for the SCIx interrupt.
26
27 - clocks: Must contain a phandle and clock-specifier pair for each entry
28 in clock-names.
29 - clock-names: Must contain "sci_ick" for the SCIx UART interface clock.
30
31Note: Each enabled SCIx UART should have an alias correctly numbered in the
32"aliases" node.
33
34Example:
35 aliases {
36 serial0 = &scifa0;
37 };
38
39 scifa0: serial@e6c40000 {
40 compatible = "renesas,scifa-r8a7790", "renesas,scifa";
41 reg = <0 0xe6c40000 0 64>;
42 interrupt-parent = <&gic>;
43 interrupts = <0 144 IRQ_TYPE_LEVEL_HIGH>;
44 clocks = <&mstp2_clks R8A7790_CLK_SCIFA0>;
45 clock-names = "sci_ick";
46 };
