According to v4l2 dt document, we add:
a camera host: ISI port.
a i2c camera sensor: ov2640 port.
to sama5d3xmb.dtsi.
In the ov2640 node, it defines the pinctrls, clocks and isi port.
In the ISI node, it also reference to a ov2640 port.

I've acked your previous patch but maybe it should be named
pinctrl_isi_pck1_as_mck to be clearer (you used the handle to pck1
below).
It's a good idea. Maybe I prefer to use the name: pinctrl_pck1_as_isi_mck ?
If you are ok with this name, in next version, I will add one more patch
in the series to do this.
And I will keep your acked-by in my previous patch.
Best Regards,
Josh Wu
