Subject: [PATCH v13 18/18] arm64: dts: rockchip: add radxa camera 8m on
rock 3a csi port
From: Michael Riesch <michael.riesch@...labora.com>
Add a device tree overlay for the Radxa Camera 8M (featuring the
Sony IMX219 image sensor) to be connected to the Radxa ROCK 3A CSI
port.
The image 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.
