Hi Sakari,
I'm replying below to your comments. I'll work on a v2 patch as soon as we get
more comments.

About "INT5648", I extracted it from the DSDT of my Lenovo Miix 310, take a look
at https://pastebin.com/ExHWYr8g .

Sorry, there is a typo here, the driver is for ov5648 (not ov5680).

Nope. As far as I know my Lenovo Miix 310 and NextBook Flexx 10.1 use this camera sensor
however the driver doesn't work on both systems due to other issues in atomisp driver itself.
As I think this driver is identical to ov2680 I decided to send this patch, I also have a
patch for hm2056 camera sensor however I'm still not sending it as I'm not properly sure
about it.
Please note: my Lenovo Miix 310 has an ov2680 camera, this is how I know that ov2680 doesn't
work too (same errors). Let me know if this patch cannot be committed until atomisp is fixed.
Please take a look at https://bugzilla.kernel.org/show_bug.cgi?id=195877 for more infos.

Ok, this makes sense to me too.

The same can be done on other atomisp drivers as far as I know. Please, let me know
about this point.

XXOV5648 comes from the original 01org patch.
INT5648 comes from my Lenovo Miix 310 DSDT (so yes, it's used at least
