|
|
|
|
- reg: The base address of the UART register bank.
|
|
|
|
- interrupts: A single interrupt specifier.
|
|
|
|
- clocks : Must contain an entry for each entry in clock-names.
|
|
See ../clocks/clock-bindings.txt for details.
|
|
- clock-names:
|
|
- "baud": The clock the baudrate is derived from
|
|
- "bus": The bus clock for register accesses (optional)
|
|
|
|
For compatibility with older device trees an unnamed clock is used for the
|
|
baud clock if the baudclk does not exist. Do not use this for new designs.
|
|
|
|
Example:
|
|
|
|
uart0: serial@11006000 {
|
|
compatible = "mediatek,mt6589-uart", "mediatek,mt6577-uart";
|
|
reg = <0x11006000 0x400>;
|
|
interrupts = <GIC_SPI 51 IRQ_TYPE_LEVEL_LOW>;
|
|
clocks = <&uart_clk>, <&bus_clk>;
|
|
clock-names = "baud", "bus";
|
|
};
