Also, I understand you followed
Documentation/devicetree/bindings/media/imx7-csi.txt and passed these
three clocks, but looking at the i.MX7D and i.MX6UL/ULL Reference
Manuals, I don't find the the descriptions for the "axi" and "dcic"
CSI clocks.
It looks like that only "mclk" is what we really need here.
Should we change the bindings and the imx7-csi driver to not request
"axi" and "dcic" clocks?
Rui, what do you think? If you agree I can send a fix for this.
Thanks
