Hi Svyatoslaw,

Thanks for the set.

I wonder how would the sensor work with the CCS driver. The register layout
appears to be very much aligned with that (I haven't checked whether there
are MSRs that depend on the mode).

Kind regards,

After deeper testing I have found that imx111 may be nokia,smia
compatible, at least most of general registers and CCS logic is
applicable. Some of registers may cause issues, for example,
"phy_ctrl_capability" = 0, 0x0 and some insane pll ranges. Maybe that
can be addressed with a firmware patch idk. The trickiest part is that
each mode requires non-standard and non-common manufacturer code
(0x3xxx ranges). If you can explain how to address these issues, I
would love to add imx111 and a few other modules into list of CCS
supported devices.

It seems to be compatible, moreover, I have a few modules which should
be compatible as well. If you had not answer I might never found this
driver, maybe you, as its maintainer, could consider adding module
names into compatible with fallback to mipi-ccs? Something like

compatible =  "sony,imx111", "mipi-ccs-1.0";

This would allow more people find this driver by grepping their sensor
model through source and reflect hardware installed in the device
better.
