Thanks, the modalias was the main missing point.
For future reference the necessary modifications for the MRF24J40MA attached
to the Raspberry Pi (using my own adapter board) are:
arch/arm/mach-bcm2708/bcm2708.c:
#ifdef CONFIG_SPI
#define MRF24J40MA_INT_GPIO_PIN 22
static struct spi_board_info bcm2708_spi_devices[] = {
{
.modalias = "mrf24j40",
.irq = BCM2708_GPIO_IRQ(MRF24J40MA_INT_GPIO_PIN),
.max_speed_hz = 12000000,
.bus_num = 0,
.chip_select = 0,
.mode = SPI_MODE_0,
}, {
.modalias = "spidev",
.max_speed_hz = 500000,
.bus_num = 0,
.chip_select = 1,
.mode = SPI_MODE_0,
}
};
#endif
arch/arm/mach-bcm2708/include/mach/gpio.h:
#define BCM2708_GPIO_IRQ(gpio) GPIO_IRQ_START+gpio
Thanks João! Thanks Alan!
