[PATCH v4 0/4] arm64: dts: renesas: sparrow-hawk: Add overlays for camera sensors

[Niklas Söderlund]

Hello,

This series adds a couple of overlays to verify the two CSI-2 busses
exposed on the V4H Sparrow Hawk board. The two busses are exposed on two
connectors labeled J1 and J2 on the board.

The first set adds overlays for the IMX219 camera sensor, one for each
connector (patch 1/4 and 2/4). A Raspberry Pi Camera Module 2 have been
used to verify the proper operation of the overlays.

The second sets adds overlays for the IMX462 camera sensors, also one
for each connector (patch 4/5 and 4/4). A DFM 36SX462-ML camera module
have been used to verify the proper operation of the overlays.

The reason two sets of overlays are needed is that the IMX219 uses
2-lanes CSI-2 D-PHY bus, while the IMX462 uses a 4-lane CSI-2 D-PHY bus.
To be able to properly test both situations on the board each sensor
needs to be able to connected to each of the two external busses.

Obviously only one sensor can be connected to J1, and one to J2 at any
given time.

See individual patches for changelog.

[PATCH v4 1/4] arm64: dts: renesas: sparrow-hawk: Add overlay for IMX219 on J1

[Niklas Söderlund]

Add an overlay to connect an IMX219 camera sensor to the J1 connector.
The IMX219 utilizes 2 CSI-2 D-PHY lanes. This enables the video capture
pipeline behind the CSI40 Rx to be enabled to process images from the
sensor.

The nodes in Sparrow Hawk root node use - instead of _ in their node names.

Here as well.

Is the "reg_" prefix needed ? Maybe "cam-J1" would be better ?

Usually we keep the related parts together, but we indeed already have
one case of interleaving.  I am not sure which style is best...

I have no real preference. The style here is only me trying to mimic
