* Fiq debugger based on UART
|
|
|
|
- compatible: "rockchip,fiq-debugger"
|
|
|
|
Compatibility with all rk30xx rk31xx rk32xx rk33xx SOCs.
|
|
|
|
- rockchip,serial-id: The uart which is used as debug port,
|
|
start from 0,1,2,3...
|
|
|
|
- rockchip,signal-irq: A hardware interrupt without source,
|
|
which is triggered by FIQ handler to call functions that
|
|
must be called in IRQ context. Often it is configured by
|
|
soc developer.
|
|
|
|
- rockchip,wake-irq: It is used to wake up fiq debugger,
|
|
but usually not used.
|
|
|
|
- rockchip,irq-mode-enable: If it is set 1, uart uses irq
|
|
instead of fiq.
|
|
|
|
- rockchip,baudrate: Only 115200 and 1500000.
|
|
|
|
Example:
|
|
fiq-debugger {
|
|
compatible = "rockchip,fiq-debugger";
|
|
rockchip,serial-id = <2>;
|
|
rockchip,signal-irq = <186>;
|
|
rockchip,wake-irq = <0>;
|
|
rockchip,irq-mode-enable = <0>;
|
|
rockchip,baudrate = <115200>;
|
|
status = "disabled";
|
|
};
