[PATCH] dts: arm64: amlogic: Add ISP related nodes for C3

[Keke Li via B4 Relay <devnull+keke.li.amlogic.com@kernel.org>]

From: Keke Li <keke.li@amlogic.com>

Add the IMX290 sensor node description to the device tree file,
which will be controlled via I2C bus with image data transmission
through MIPI CSI-2 interface.

Add CSI-2, adapter and ISP nodes for C3 family.

Signed-off-by: Keke Li <keke.li@amlogic.com>
---
The C3 ISP driver and device-tree bindings have been
submitted. To facilitate using the C3 ISP driver, the
related device nodes need to be added.
