| 2 | |
| 3 | Required properties: |
| 4 | - compatible : "snps,arc-uart" |
| 5 | - reg : offset and length of the register set for the device. |
| 6 | - interrupts : device interrupt |
| 7 | - clock-frequency : the input clock frequency for the UART |
| Vineet Gupta | 11c62d4 | 2013-02-11 14:11:41 +0530 | [diff] [blame] | 8 | - current-speed : baud rate for UART |
| Vineet Gupta | ea28fd5 | 2013-01-11 11:50:23 +0530 | [diff] [blame] | 9 | |
| 10 | e.g. |
| 11 | |
| 12 | arcuart0: serial@c0fc1000 { |
| 13 | compatible = "snps,arc-uart"; |
| 14 | reg = <0xc0fc1000 0x100>; |
| 15 | interrupts = <5>; |
| 16 | clock-frequency = <80000000>; |
| Vineet Gupta | 11c62d4 | 2013-02-11 14:11:41 +0530 | [diff] [blame] | 17 | current-speed = <115200>; |
| Vineet Gupta | ea28fd5 | 2013-01-11 11:50:23 +0530 | [diff] [blame] | 18 | status = "okay"; |
| 19 | }; |
| 20 | |
| 21 | Note: Each port should have an alias correctly numbered in "aliases" node. |
| 22 | |
| 23 | e.g. |
| 24 | aliases { |
| 25 | serial0 = &arcuart0; |
| 26 | }; |
