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 | }; |
