I think you could omit this, as the check is present in the Makefile in the
subdirectory.

Please not wrap like this; instead you can do that between the arguments
and before the function name, but not elsewhere.

u32 would seem like a more appropriate return type.

Please document in DT bindings how the lane numbering goes.

Perhaps "mtk" prefix here? It's used by the rest of the driver. Or remove
the underscore.

What do these bits mean? Please add #defines for them in the header. The
same applies to similar numerical values used throughout the driver.

Could you use one of the macros you use to access these registers, or
writel() or such?

You appear to be missing the link_validate callback. Most likely
v4l2_subdev_link_validate_default will be fine.

This seems like a leftover from the development time. If you'd like to keep
it or something like that, use dev_dbg().

In general, I'd suggest parsing the information from the firmware during
probe rather than here. See e.g. the omap3isp driver for an example. You
seem to have a function below for this purpose; it's just content that's
missing in it. :-)

Are the clocks needed by the seninf, or the sensors? If they're the
sensors, then please use the clock framework to expose them to the sensor
drivers. Otherwise they should go to the driver's runtime PM callbacks.

If you have 12 pads on a single subdev with 4 sinks, what are the 8 source
pads for? I think this would necessitate some documentation under
Documentation/media/v4l-drivers/ . There may be a need to discuss the
design, too. Do you need the S_ROUTING IOCTL support to configure this, for
instance?
