Thanks for creating an emulator and test! However instead of having the test write register values directly into the emulator, you can use the emulator sensor backend API.
The generic sensor test will then validate your new temperature sensor an emulator.
Your emulator code needs to implement the 'set_channel` API, which will internally write the correct registers corresponding to the set operation.
See the akm09918c emulator for an example.

These public routines shouldn't be needed once you use the emulator backend model.

Yeah sorry, that was an accidental merge commit |

This sort of thing is exactly why we need to support channel type and index pairs and not just channel type

Are there any open issues/proposals to to do this?
This could also be modeled as a multi-function device, with each temperature sensor nested under a parent device. But that seems a little heavyweight.

It's being discussed in #61163, though to the best of my knowledge, there is no dedicated issue about this.

MFD for that seems incredibly overkill for this, device specific channels seems reasonable to close the gap and get the code in, easy enough to change it to subchannel later.

Would also be nice to add some constants for the numbers, e.g.
#define F75303_TEMP_SAMPLE_INT_SHIFT (3)
#define F75303_TEMP_SAMPLE_FRAC_MASK GENMASK(2,0)
#define F75303_TEMP_SAMPLE_MICROCELSIUS_PER_BIT (125000)
These don't need to go in the header as neither tests nor applications need these.
