IRQs from peripherals such as i2c/uart/ethernet come via the AXI Interrupt controller. Select it in Kconfig for xilfpga and add the DT node Signed-off-by: Zubair Lutfullah Kakakhel <redacted> --- V1 -> V2 Renamed select XILINX_INTC to select XILINX_AXI_INTC --- arch/mips/Kconfig | 1 + arch/mips/boot/dts/xilfpga/nexys4ddr.dts | 12 ++++++++++++ 2 files changed, 13 insertions(+)
