It can also be programmed to provide raw ADC code, but the secure software on 8996 programs it to provide real temperatures and also does the needed calibrations. We check the valid bit to ensure valid data is read by the AHB master. And the spec recommends the below algorithm to read data 3 consecutive times, which takes care of the worst case delay taken to propagate the updated data to the register.

Also GCC/TSENS are part of a domain thats not always ON. Hence add .suspend and .resume hooks to save and restore some of the inited register context. Also 8960 family have some of the TSENS init sequence thats required to be done by the HLOS driver (some later versions of TSENS do not export these registers to non-secure world, and hence need these initializations to be done by secure bootloaders) 8660 from the same family has just one sensor and hence some register offset/layout differences which need special handling in the driver.
