how to get interrupt pin from the device tree?

[lonerwolf]

Code: Select all

spi1: spi@f8008000 {
				cs-gpios = <&pioC 25 0>, <0>, <0>, <&pioD 16 0>;
				status = "okay";
			
				device@0{
					compatible="spidev";
					reg=<0>;
					spi-max-frequency=<5000000>;
                                        interrupts = <6 IRQ_TYPE_LEVEL_HIGH 0>;//here
				};
			};

i want usr the PD31 pin to a ext interrupt, how to write here?
in spi.c,spi->irq = irq_of_parse_and_map(nc, 0); this func get the interrupt,how can i do?

What kernel version are you using, and from what repository?
This isn't the proper string for most versions.

What are you really trying to do?
The spidev driver, unless modified, will not use such DT configuration info.

in spi.c,spi->irq = irq_of_parse_and_map(nc, 0); this func get the interrupt,how can i do?

You probably shouldn't be looking at spi.c.
Read about the spi drivers organization in the kernel's Documentation directory.
