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.
