Subject: [PATCH v3 5/5] ARM: dts: bcm2711: Add Unicam DT nodes
Date: Mon,  2 Nov 2020 17:52:58 +0100	[thread overview]
Message-ID: <20201102165258.408049-6-jacopo@jmondi.org> (raw)
In-Reply-To: <20201102165258.408049-1-jacopo@jmondi.org>

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

The Unicam IP cores are CSI-2/CCP2 receivers. They are part of VC4, but
can be controlled directly from the operating system without going
through the VPU firmware. Exposes them as DT nodes.
