[PATCH 0/6] MIPS: xilfpga: Use irq-xilinx-intc

[PATCH 0/6] MIPS: xilfpga: Use irq-xilinx-intc

[Zubair Lutfullah Kakakhel]

Hi,

The interrupt controller driver was in arch/microblaze.
The patches to move the driver out from arch/microblaze
to drivers/irqchip/irq-xilinx-intc.c have now been accepted [1]

Hence, xilfpga can make use of the driver in v4.10.

These patches do the following:
- Use the irqchip driver
- Add Device Tree nodes for various peripherals that were blocked
- Enable those drivers in the defconfig

Based on v4.9-rc6

Regards,
ZubairLK
