Subject: [PATCH v2 15/15] ARM: dts: bcm2711: Add the CEC interrupt controller
Date:   Mon, 11 Jan 2021 15:23:09 +0100
Message-Id: <20210111142309.193441-16-maxime@cerno.tech>

The CEC and hotplug interrupts go through an interrupt controller shared
between the two HDMI controllers.

Let's add that interrupt controller and the interrupts for both HDMI
controllers
