When we have dts support added to bcma, I would like to remove chipcommonA from dtsi and add a chipcommon as a child of axi. > > It seems that for some reason both of them use IRQ 85, while the IRQ > for ChipCommon is 117 I believe. That's the same. In the dtsi file it says: interrupts = <GIC_SPI 85 IRQ_TYPE_LEVEL_HIGH>; this will result in the IRQ number 117, when it is GIC_SPI you have to add 32 to the irq number to get the actual number which will be given to request_irq().
