Merge "thermal: tsens: Update TSENS property for reading efuse data"

	       should be "qcom,msmfalcon-tsens" for falcon TSENS driver.

	       The compatible property is used to identify the respective fusemap to use

	       for the corresponding SoC.

- reg : offset and length of the TSENS registers.

- reg : offset and length of the QFPROM registers used for storing

	the calibration data for the individual sensors.

- reg : offset and length of the TSENS registers with associated property in reg-names

	as "tsens_physical" and QFPROM registers with associated property in reg-names

	as "tsens_eeprom_physical". The efuse registers are used for storing

	the calibration data for the individual sensors. If the gain and offset are

	programmed by the TSENS control registers then adding the QFPROM register property

	is optional.

- reg-names : resource names used for the physical address of the TSENS

	      registers, the QFPROM efuse primary calibration address region,

	      Should be "tsens_physical" for physical address of the TSENS,

	      "tsens_eeprom_physical" for physical address where primary

	      calibration data is stored. This includes the backup

	      calibration address region if TSENS calibration data is stored

	      in the region.

	      in the region. The reg-name "tsens_eeprom_physical" property is

	      optional if the gain and offset are programmed by the TSENS

	      control registers and the status registers directly reports the TSENS

	      temperature readings.

- interrupts : TSENS interrupt to notify Upper/Lower temperature threshold.

- interrupt-names: Should be "tsens-upper-lower" for temperature threshold.

		   Add "tsens-critical" for Critical temperature threshold notification

- qcom,slope : One point calibration characterized slope data for each

	       sensor used to compute the offset. Slope is represented

	       as ADC code/DegC and the value is multipled by a factor

	       of 1000.

	       of 1000. If gain and offset are programmed by the TSENS control

	       registers then this property is optional.
