* Renesas SH-Mobile Serial Communication Interface
Required properties:
- compatible: Must contain one of the following:
- "renesas,scif-r8a7790" for R8A7790 (R-Car H2) SCIF compatible UART.
- "renesas,scifa-r8a7790" for R8A7790 (R-Car H2) SCIFA compatible UART.
- "renesas,scifb-r8a7790" for R8A7790 (R-Car H2) SCIFB compatible UART.
- "renesas,hscif-r8a7790" for R8A7790 (R-Car H2) HSCIF compatible UART.
- "renesas,scif-r8a7791" for R8A7791 (R-Car M2) SCIF compatible UART.
- "renesas,scifa-r8a7791" for R8A7791 (R-Car M2) SCIFA compatible UART.
- "renesas,scifb-r8a7791" for R8A7791 (R-Car M2) SCIFB compatible UART.
- "renesas,hscif-r8a7791" for R8A7791 (R-Car M2) HSCIF compatible UART.
- "renesas,scif" for generic SCIF compatible UART.
- "renesas,scifa" for generic SCIFA compatible UART.
- "renesas,scifb" for generic SCIFB compatible UART.
- "renesas,hscif" for generic HSCIF compatible UART.
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.
Example:
aliases {
serial0 = &scifa0;
};
scifa0: serial@e6c40000 {
compatible = "renesas,scifa-r8a7790", "renesas,scifa-generic";
reg = <0 0xe6c40000 0 64>;
interrupt-parent = <&gic>;
interrupts = <0 144 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&mstp2_clks R8A7790_CLK_SCIFA0>;
clock-names = "sci_ick";
};
