Merge "qpnp-fg-gen3: add support to configure and handle delta battery temperature"

		    loaded earlier by bootloader doesn't match with the profile

		    available in the device tree.

- qcom,cl-start-capacity

	Usage:      optional

	Value type: <u32>

	Definition: Battery SOC threshold to start the capacity learning.

		    If this is not specified, then the default value used

		    will be 15.

- qcom,cl-min-temp

	Usage:      optional

	Value type: <u32>

	Definition: Lower limit of battery temperature to start the capacity

		    learning. If this is not specified, then the default value

		    used will be 150. Unit is in decidegC.

- qcom,cl-max-temp

	Usage:      optional

	Value type: <u32>

	Definition: Upper limit of battery temperature to start the capacity

		    learning. If this is not specified, then the default value

		    used will be 450 (45C). Unit is in decidegC.

- qcom,cl-max-increment

	Usage:      optional

	Value type: <u32>

	Definition: Maximum capacity increment allowed per capacity learning

		    cycle. If this is not specified, then the default value

		    used will be 5 (0.5%). Unit is in decipercentage.

- qcom,cl-max-decrement

	Usage:      optional

	Value type: <u32>

	Definition: Maximum capacity decrement allowed per capacity learning

		    cycle. If this is not specified, then the default value

		    used will be 100 (10%). Unit is in decipercentage.

- qcom,cl-min-limit

	Usage:      optional

	Value type: <u32>

	Definition: Minimum limit that the capacity cannot go below in a

		    capacity learning cycle. If this is not specified, then

		    the default value is 0. Unit is in decipercentage.

- qcom,cl-max-limit

	Usage:      optional

	Value type: <u32>

	Definition: Maximum limit that the capacity cannot go above in a

		    capacity learning cycle. If this is not specified, then

		    the default value is 0. Unit is in decipercentage.

- qcom,fg-jeita-hyst-temp

	Usage:      optional

	Value type: <u32>

	Definition: Hysteresis applied to Jeita temperature comparison.

		    Possible values are:

			0 - No hysteresis

			1,2,3 - Value in Celsius.

- qcom,fg-batt-temp-delta

	Usage:      optional

	Value type: <u32>

	Definition: Battery temperature delta interrupt threshold. Possible

		    values are: 2, 4, 6 and 10. Unit is in Kelvin.
