| 1 | Binding for Conexant Digicolor USART |
| 2 | |
| 3 | Note: this binding is only applicable for using the USART peripheral as |
| 4 | UART. USART also support synchronous serial protocols like SPI and I2S. Use |
| 5 | the binding that matches the wiring of your system. |
| 6 | |
| 7 | Required properties: |
| 8 | - compatible : should be "cnxt,cx92755-usart". |
| 9 | - reg: Should contain USART controller registers location and length. |
| 10 | - interrupts: Should contain a single USART controller interrupt. |
| 11 | - clocks: Must contain phandles to the USART clock |
| 12 | See ../clocks/clock-bindings.txt for details. |
| 13 | |
| 14 | Note: Each UART port should have an alias correctly numbered |
| 15 | in "aliases" node. |
| 16 | |
| 17 | Example: |
| 18 | aliases { |
| 19 | serial0 = &uart0; |
| 20 | }; |
| 21 | |
| 22 | uart0: uart@f0000740 { |
| 23 | compatible = "cnxt,cx92755-usart"; |
| 24 | reg = <0xf0000740 0x20>; |
| 25 | clocks = <&main_clk>; |
| 26 | interrupts = <44>; |
| 27 | }; |
