I use the following code in the drive for gpio and interrupt
for (I=0; i<(sizeof (pins_desc)/sizeof (pins_desc [0])); I++)
{
Res=platform_get_resource (pdev IORESOURCE_IRQ, I);//get irq resource
If (res)
{
Pins_desc [I] irq=res - & gt; The start;
Printk (" get irq: % d \ n ", pins_desc [I] irq);
}
The else
{
Printk (" can 't get irq: % d \ n ", I);
return -1;
}
Pins_desc [I]. Pin=of_get_named_gpio (dev_node, "eint - pins", I);//to look for in the node name for eint - pins attribute
Printk (" pins_desc [% d] pin=% d \ n ", I, pins_desc [I] pin);
}
Print out the following fields
Get an irq: 1
Pins_desc [0]. Pin=84
Get an irq: 2
Pins_desc [1]. The pin=86
Get an irq: 3
Pins_desc [2]. Pin=95
Get an irq: 15
Pins_desc [3]. The pin=103
The pin Numbers and gpio is actually how a corresponding relationship?
