How to convert BMM150 rhall to temperature?

[vjh]

Hello, I would like to convert the rhall value output by the BMM150 to a temperature. How to do this?

rhall will be used by API (in following link) to convert the register data into physical data with temperature compensation. 

It also use some trimming register inside BMM150.

But you can't directly convert rhall to temperature value.
