Hello,

This is v3 of the series 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.

In v3, I updated the device tree bindings based on Robs review comments. In
the driver itself, only the powerdown gpio name has changed, to follow the dt
binding change.

Michael
