Subject: [PATCH 1/2] ARM: dts: r7s9210: Add IRQC device node
Date: Tue, 4 Jun 2019 15:09:13 -0500	[thread overview]
Message-ID: <20190604200914.64896-2-chris.brandt@renesas.com> (raw)
In-Reply-To: <20190604200914.64896-1-chris.brandt@renesas.com>

Enable support for the IRQC on RZ/A2M, which is a small front-end to the
GIC.  This allows to use up to 8 external interrupts with configurable
sense select.
