I developed one ethernet cape that uses the SPI. The configuration node
bellows is working because I did a change in the device drive to
handle the interrupt number as GPIO number (gpio1_15) and included code to
map one interrupt ( for 47 I am getting IRQ 191).
If I understand correctly I shouldn't have to apply any patch, the
interrupt should be described in the device tree so that the SPI drive could
understand what interrupt has to be assigned. When I don't apply the patch,
the SPI assign the IRQ 63 (47 to 63 ???) that doesn't work.
I would like to know how should be GPIO interrupt configuration to use the
drive as is.
&spi1 {
pinctrl-names = "default";
pinctrl-0 = <&spi1_pins>;
status = "okay";
spidev2: spi@0 {
compatible = "microchip,enc28j60";
reg = <0>;
spi-max-frequency = <24000000>;
interrupts = <47>;
};
};
Sincerely,
Ventura
