Hello!
I am trying to use LPC wire on my Intel Atom E3800 based board for communication with my custom FPGA device. There is sja1000 CAN transivere realized on this device. So I can work with this device by polling with no problem. But for some strange reason, I don’t get interrupts from this device. I see by oscilloscope serial irq requests from CPU and the device is response, but my OS (Linux) does not get this interrupts. Here my board directory https://github.com/yanvasilij/nefteavtomatika. I think I have a similar problem like this https://mail.coreboot.org/pipermail/coreboot/2016-January/080839.html. But my device use IRQ7, not IRQ4. So I made like described here https://mail.coreboot.org/pipermail/coreboot/2016-January/080848.html. There are adviced to me to describe my LPC device in devicetree. But should I realy to do it, if I working with LPC bus directly from Linux? What am I doing wrong? What am I doing wrong? May be I have a problem with IRQ route? Linux dmesg output and .config are in attachments.
