| * 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"; |
| }; |
