Subject: [PATCH v12 18/18] arm64: dts: rockchip: add overlay for radxa
camera 8m
From: Michael Riesch <michael.riesch@...labora.com>
Add a device tree overlay for the Radxa Camera 8M featuring the Sony
IMX219 image sensor. The sensor is connected to the RK3568 VICAP MIPI
CSI-2 port, since as at the time of writing this there is no mainline
support for the RK3568 ISP.
