Hi,
Yes, you need to specify irq.
On my code:
{
.modalias = "mrf24j40", //jpb
//.platform_data // not need
.irq = OMAP_GPIO_IRQ(AM335XEVM_MRF24J40_IRQ_GPIO),
.max_speed_hz = 12000000,
.bus_num = 2,
.chip_select = 0,
},
Otherwise, in the request_irq() function on mrf24j40.c, is gonna be
requested probably the irq 0 or trash
