Makes sense, that's why my kernel compilation passed and I didn't
these errors. Thanks for the command, I will verify dts for
correctness in next patch series.

I was assuming that this would be a part of the board specific dtsi or
dts entry where the isp node would be overriden and the i2c camera
port
and the isp port remote-endpoints would be connected. I had this as a
part of my first patch series. However I was advised by Helen to not
include the ov5647
dtsi as it isn't hardwired to the SoC and resides on an camera adapter board.
Should this be defined without the remote-endpoint phandle since we
don't know exactly which sensor gets connected in this dtsi file ?

The tinkerboard debian kernel (where I referred to for this patch)
didn't have it defined for the DPHY. I would guess that it would be
the same as the ISP i.e. RK3288_PD_VIO,
does anyone know the answer to this or do I have to reach out to
Rockchip engineering ?
