Yes, this driver is also used by Exynos4210 and Exynos4412, notably by the Galaxy S3 series.
They don't use the parallel ports, but rather the CSIS.  I don't believe I've broken support
for that, but I don't have the hardware to test.

My other remaining concern is whether to adjust the camera port A/camera port B to match the
device tree documentation or to update the documentation to match the driver.  I decided to
update the driver in these patches, but it is much simpler to simply update the binding doc.
The only mainline user of the parallel ports is the Goni dev board which appears to be setup
for the driver way of numbering as opposed to the binding doc.  I have no strong preference
on which way to actually go.

Thanks, that would be appreciated,
