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.

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
