2016-11-29powerpc/virtex: Use generic xilinx irqchip driverZubair Lutfullah Kakakhel1-1/+2
The Xilinx interrupt controller driver is now available in drivers/irqchip. Switch to using that driver.

2016-11-29irqchip/xilinx: Try to fall back if xlnx,kind-of-intr not providedZubair Lutfullah Kakakhel1-2/+2
The powerpc dts file does not have the xlnx,kind-of-intr property. Instead of erroring out, give a warning instead. And attempt to continue to probe the interrupt controller while assuming kind-of-intr is 0x0 as a fall back.

2016-11-29irqchip/xilinx: Add support for parent intcZubair Lutfullah Kakakhel1-2/+32
The MIPS based xilfpga platform has the following IRQ structure Peripherals --> xilinx_intcontroller -> mips_cpu_int controller Add support for the driver to chain the irq handler Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2016-11-29irqchip/xilinx: Rename get_irq to xintc_get_irqZubair Lutfullah Kakakhel1-1/+1
Now that the driver is generic and used by multiple archs, get_irq is too generic. Rename get_irq to xintc_get_irq to avoid any conflicts Acked-by: Michal Simek <michal.simek@xilinx.com> Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2016-11-29irqchip/xilinx: Restructure and use jump label apiZubair Lutfullah Kakakhel1-52/+66
Add a global structure to house various variables. And cleanup read/write handling by using jump label api. Tested-by; Michal Simek <michal.simek@xilinx.com> Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2016-11-29irqchip/xilinx: Clean up print messagesZubair Lutfullah Kakakhel1-9/+9
Remove __func__ and prefix irq-xilinx in various debug prints Acked-by: Michal Simek <michal.simek@xilinx.com> Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2016-11-29microblaze/irqchip: Move intc driver to irqchipZubair Lutfullah Kakakhel1-0/+196
The Xilinx AXI Interrupt Controller IP block is used by the MIPS based xilfpga platform and a few PowerPC based platforms. Move the interrupt controller code out of arch/microblaze so that it can be used by everyone Tested-by: Michal Simek <michal.simek@xilinx.com> Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
