Subject: [PATCH v2 14/15] ARM: dts: bcm2711: Add the BSC interrupt controller
Date: Mon, 11 Jan 2021 15:23:08 +0100 [thread overview]
Message-ID: <20210111142309.193441-15-maxime@cerno.tech> (raw)
In-Reply-To: <20210111142309.193441-1-maxime@cerno.tech>
The BSC controllers used for the HDMI DDC have an interrupt controller
shared between both instances. Let's add it to avoid polling.
