Unfortunately that ID is used by the windows Bosch drivers for numerous
completely incompatible devices.  So we can't do soft matching on this one.
We need to know what the device actually is and add explicit support for
it.

So it's going to take some detective work to find a device with ID 12.

Any other information on what device this might be?

I looked through all the bosch accelerator datasheets I could find and the
closest i could get was:

CHIP     chip_id
BMA423 - 0x13
BMA456 - 0x16

I'm thinking it may be the BMA422 but that datasheet isn't available for some
reason.   I did also ask in their forums but no responses.  Unfortunately, I
don't think it's an easy task to disassemble the screen.

Without a datasheet this is hard, but you 'could' try just hacking in the
ID in the driver and see what works?  Particularly if scales match up with the
stuff on the flyer that is available for the BMA422.

I did try hard-coding each of the 5 chip_ids from bmc150_accel_chip_info_tbl in
bmc150-accel-core.c, unfortunately none of them worked.  monitor-sensor would
not register any changes when moving the display panel.

I did find this which does confirm it is a BMA422 chip based on the 0x12
chip_id:

I'm going to mark this as resolved as we Bosch will not provide the datasheet
for this chip.
