| 34 | When compatible with the generic version, nodes must list the | |
| 35 | SoC-specific version corresponding to the platform first followed by the | |
| 36 | generic version. | |
| 37 | ||
| 38 | - reg: Base address and length of the I/O registers used by the UART. | |
| 39 | - interrupts: Must contain an interrupt-specifier for the SCIx interrupt. | |
| 40 | ||
| 41 | - clocks: Must contain a phandle and clock-specifier pair for each entry | |
| 42 | in clock-names. | |
| 43 | - clock-names: Must contain "sci_ick" for the SCIx UART interface clock. | |
| 44 | ||
| 45 | Note: Each enabled SCIx UART should have an alias correctly numbered in the | |
| 46 | "aliases" node. | |
| 47 | ||
| 48 | Example: | |
| 49 | aliases { | |
| 50 | serial0 = &scifa0; | |
| 51 | }; | |
| 52 | ||
| 53 | scifa0: serial@e6c40000 { | |
| 25eb50b9 | 54 | compatible = "renesas,scifa-r8a7790", "renesas,scifa"; |

| 58 | clocks = <&mstp2_clks R8A7790_CLK_SCIFA0>; | |
