* Maxim MAX310X advanced Universal Asynchronous Receiver-Transmitter (UART)
|
|
|
|
Required properties:
|
|
- compatible: Should be one of the following:
|
|
- "maxim,max3107" for Maxim MAX3107,
|
|
- "maxim,max3108" for Maxim MAX3108,
|
|
- "maxim,max3109" for Maxim MAX3109,
|
|
- "maxim,max14830" for Maxim MAX14830.
|
|
- reg: SPI chip select number.
|
|
- interrupts: Specifies the interrupt source of the parent interrupt
|
|
controller. The format of the interrupt specifier depends on the
|
|
parent interrupt controller.
|
|
- clocks: phandle to the IC source clock.
|
|
- clock-names: Should be "xtal" if clock is an external crystal or
|
|
"osc" if an external clock source is used.
|
|
|
|
Optional properties:
|
|
- gpio-controller: Marks the device node as a GPIO controller.
|
|
- #gpio-cells: Should be two. The first cell is the GPIO number and
|
|
the second cell is used to specify the GPIO polarity:
|
|
0 = active high,
|
|
1 = active low.
|
|
|
|
Example:
|
|
|
|
/ {
|
|
clocks {
|
|
spi_uart_clk: osc_max14830 {
|
|
compatible = "fixed-clock";
|
|
#clock-cells = <0>;
|
|
clock-frequency = <3686400>;
|
|
};
|
|
|
|
};
|
|
};
|
|
|
|
&spi0 {
|
|
max14830: max14830@0 {
|
|
compatible = "maxim,max14830";
|
|
reg = <0>;
|
|
clocks = <&spi_uart_clk>;
|
|
clock-names = "osc";
|
|
interrupt-parent = <&gpio3>;
|
|
interrupts = <7 IRQ_TYPE_LEVEL_LOW>;
|
|
gpio-controller;
|
|
#gpio-cells = <2>;
|
|
};
|
|
};
