| 2 | |
| 3 | The MSM serial UART hardware is designed for low-speed use cases where a |
| 4 | dma-engine isn't needed. From a software perspective it's mostly compatible |
| 5 | with the MSM serial UARTDM except that it only supports reading and writing one |
| 6 | character at a time. |
| 7 | |
| 8 | Required properties: |
| 9 | - compatible: Should contain "qcom,msm-uart" |
| 10 | - reg: Should contain UART register location and length. |
| 11 | - interrupts: Should contain UART interrupt. |
| 12 | - clocks: Should contain the core clock. |
| 13 | - clock-names: Should be "core". |
| 14 | |
| 15 | Example: |
| 16 | |
| 17 | A uart device at 0xa9c00000 with interrupt 11. |
| 18 | |
| 19 | serial@a9c00000 { |
| 20 | compatible = "qcom,msm-uart"; |
| 21 | reg = <0xa9c00000 0x1000>; |
| 22 | interrupts = <11>; |
| 23 | clocks = <&uart_cxc>; |
| 24 | clock-names = "core"; |
| 25 | }; |
