[v3,5/5] ARM: dts: bcm2711: Add Unicam DT nodes
Commit Message
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.
