[PATCH V3 0/4] Add support for IPQ5018 tsens

[Sricharan R]

IPQ5018 has tsens V1.0 IP with 4 sensors and 1 interrupt.
There is no RPM present in the soc to do tsens early enable.
Adding support for the same here.

[v3]
	*) Added the tsens-ipq5018 as  new binding without rpm
        *) Added Dmitry's Reviewed tag
        *) Fixed Dmitry's comments for error checks in init_ipq5018
        *) Ordered the qfprom device node properties

[v2]
	*) Sorted the compatible and removed example
	*) Fixed the name for new tsens_feature
	*) Used tsend_calibrate_common instead of legacy
	   and addressed comments from Dmitry.
	*) Squashed patch 3 & 4
	*) Fixed node names, order and added qfprom cells
            for points seprately
	*) Squashed patch 6 & 7

Then why do you allow two interrupts?

You miss now description of interrupts, like the other variants have.

Description? So you still allow two interrupts? No, this must be
constrained in allOf:if:then.

  ok, it should be fine to add this new compatible to the existing
  allof:if:then block of v1 targets ? (Because they also have same
  single interrupt (uplow) constraint)

[PATCH V3 2/4] thermal/drivers/qcom: Add new feat for soc without rpm

[Sricharan R]

From: Sricharan Ramabadhran <quic_srichara@quicinc.com>

In IPQ5018, Tsens IP doesn't have RPM. Hence the early init to
enable tsens would not be done. So add a flag for that in feat
and skip enable checks. Without this, tsens probe fails.

[PATCH V3 4/4] arm64: dts: qcom: ipq5018: Add tsens node

[Sricharan R]

From: Sricharan Ramabadhran <quic_srichara@quicinc.com>

IPQ5018 has tsens V1.0 IP with 4 sensors.
There is no RPM, so tsens has to be manually enabled. Adding the tsens
and nvmem node and IPQ5018 has 4 thermal sensors (zones). With the
critical temperature being 120'C and action is to reboot. Adding all
the 4 zones here.
