[PATCH v10 0/7] Add TSENS support for IPQ5332, IPQ5424

[PATCH v10 0/7] Add TSENS support for IPQ5332, IPQ5424

[Manikanta Mylavarapu]

IPQ5332 uses tsens v2.3.3 IP with combined interrupt for
upper/lower and critical. IPQ5332 does not have RPM and
kernel has to take care of TSENS enablement and calibration.

IPQ5424 also uses same tsens v2.3.3 IP and it's similar to IPQ5332
(no RPM) hence add IPQ5424 support in this series itself.

This patch series adds the temperature sensor enablement,
calibration support for IPQ5332 and IPQ5424.

Changes in V10:
	- Fixed all review comments from Konrad Dybico,Christophe
	  JAILLET
	- Detailed change logs are added to the respective patches

[PATCH v10 1/7] dt-bindings: thermal: tsens: Add ipq5332, ipq5424 compatible

[Manikanta Mylavarapu]

From: Praveenkumar I <quic_ipkumar@quicinc.com>

The IPQ5332 and IPQ5424 use TSENS v2.3.3 IP with combined interrupt.
RPM is not available in these SoCs, hence adding new compatible
to have the sensor enablement and calibration function. Also add
nvmem-cell-names.

[PATCH v10 3/7] thermal/drivers/tsens: Add TSENS enable and calibration support for V2

[Manikanta Mylavarapu]

From: Praveenkumar I <quic_ipkumar@quicinc.com>

SoCs without RPM need to enable sensors and calibrate them from the kernel.
The IPQ5332 and IPQ5424 use the tsens v2.3.3 IP and do not have RPM.
Therefore, add a new calibration function for V2, as the tsens.c calib
function only supports V1. Also add new feature_config, ops and data for
IPQ5332, IPQ5424.

Although the TSENS IP supports 16 sensors, not all are used. The hw_id
is used to enable the relevant sensors.
