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.
