Btw. do note that you may get a warning due to this from the CSI-2 bus

The only reference to possible values to this parameter is given by
table in [0], can you point me out the formula for imx7 in the
documentation?

I don't know imx7 but the other CSI-2 drivers need no such system specific

Hum, I think there is at least one more (which this is compliant) that
also use this configuration parameter. [0]
