[PATCH 0/5] 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 2/5 and 3/5). 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 5/5). 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.

Patch 1/5 is a drive-by fix that adds an missing install target for an 
existing sparrow-hawk overlay. It could have been posted as a separate 
patch but could have caused potential conflicts so I kept it in this 
series.

Is the 'status = "okay"' property needed for these regulators ? I think 
'status = "okay"' is the default behavior if "status" property is not 
present , so 'status = "okay"' is superfluous here.

Indeed you are correct, the status property for the fixed regulators are 
superfluous. Will drop in next version, thanks for teaching me something 
new.

[PATCH 5/5] arm64: dts: renesas: sparrow-hawk: Add overlay for IMX462 on J2

[Niklas Söderlund]

Add an overlay to connect an IMX462 camera sensor to the J2 connector.
The IMX462 utilizes 4 CSI-2 D-PHY lanes. This enables the video capture
pipeline behind the CSI41 Rx to be enabled to process images from the
sensor.
