Subject: [PATCH 1/2] ARM: dts: TS-4800: add FPGA's IRQ controller support
Date: Tue, 17 May 2016 16:16:29 -0400 [thread overview]
Message-ID: <1463516190-10606-1-git-send-email-damien.riegel@savoirfairelinux.com> (raw)
Enable FPGA's IRQ controller. It is in charge of dispatching interrupts
generated by IPs in the FPGA. The SoC is notified that an interrupt
occurred through a GPIO.
