This is v9 of the series to for adding the isl7998x driver [0].

The isl7998x is an analog video to MIPI CSI-2 or BT.656 converter. The dt
binding describes only the isl79987 chip, which supports MIPI CSI-2. The
driver could be extended to handle isl79988 (for BT.656), too, but this isn't
implemented.

v9 fixes the following warning when running the dt_binding_check, by removing
the clock-lanes property from the example and adding the data-lanes property
to the specification.

	isl7998x_mipi@44: ports:port@0:endpoint: Unevaluated properties are not allowed ('clock-lanes', 'data-lanes' were unexpected)
