| * 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";
| };
