| 2 | |
| 3 | Required properties: |
| 4 | - compatible : "snps,dw-apb-uart" |
| 5 | - reg : offset and length of the register set for the device. |
| 6 | - interrupts : should contain uart interrupt. |
| 7 | - clock-frequency : the input clock frequency for the UART. |
| 8 | |
| 9 | Optional properties: |
| 10 | - reg-shift : quantity to shift the register offsets by. If this property is |
| 11 | not present then the register offsets are not shifted. |
| 12 | - reg-io-width : the size (in bytes) of the IO accesses that should be |
| 13 | performed on the device. If this property is not present then single byte |
| 14 | accesses are used. |
| 15 | |
| 16 | Example: |
| 17 | |
| 18 | uart@80230000 { |
| 19 | compatible = "snps,dw-apb-uart"; |
| 20 | reg = <0x80230000 0x100>; |
| 21 | clock-frequency = <3686400>; |
| 22 | interrupts = <10>; |
| 23 | reg-shift = <2>; |
| 24 | reg-io-width = <4>; |
| 25 | }; |
