Subject: [Patch v5 08/12] MIPS: xilfpga: Use Xilinx Interrupt Controller
Date: Mon, 17 Oct 2016 17:52:52 +0100 [thread overview]
Message-ID: <1476723176-39891-9-git-send-email-Zubair.Kakakhel@imgtec.com> (raw)
In-Reply-To: <1476723176-39891-1-git-send-email-Zubair.Kakakhel@imgtec.com>
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>

V4 -> V5
Rebase to v4.9-rc1
Renamed XILINX_AXI_INTC to XILINX_INTC
V3 -> V4
No change
V2 -> V3
No change
V1 -> V2
Renamed select XILINX_INTC to select XILINX_AXI_INTC
