MIPS: xilfpga: Use Xilinx Interrupt Controller
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 <Zubair.Kakakhel@imgtec.com> Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/14592/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
