[Dmitry Baryshkov]

Improve thermal monitoring on 8450-HDK board. First set of patches fix
c&p typos in PMIC include files (mea culpa). The rest of patches enable
ADC-TM usage on the SM8450 HDK.

[PATCH 1/7] arm64: dts: qcom: pm8350: fix thermal zone name

[Dmitry Baryshkov]

[PATCH 4/7] arm64: dts: qcom: pmk8350: fix ADC-TM compatible string

[Dmitry Baryshkov]

The commit b2de43136058 ("arm64: dts: qcom: pmk8350: Add peripherals for
pmk8350") for the ADC TM (thermal monitoring device) have used the
compatible string from the vendor kernel ("qcom,adc-tm7"). Use the
proper compatible string that is defined in the upstream kernel
("qcom,spmi-adc-tm5-gen2").

Well actually, adc-tm7 would be the correct compatible (PM8350X is PMIC7)
but it never landed on the driver side..

I also thought so (and started implementing adc-tm7), but then I
stumbled upon the commit 96f6f333bcf0 ("thermal/drivers/qcom: Add
support for PMIC5 Gen2 ADCTM"), which clearly tells:

    Add support for PMIC5 Gen2 ADC_TM, used on PMIC7 chips. It is a
    close counterpart of PMIC7 ADC and has the same functionality as
    PMIC5 ADC_TM, for threshold monitoring and interrupt generation.
    It is present on PMK8350 alone, ....

So, this is the right compatible for PMK8350.

That's.. strange.. Did you confirm this with schematics, or even better,

[PATCH 6/7] arm64: dts: qcom: sm8450-hdk: define DIE_TEMP channels

[Dmitry Baryshkov]

Declare the DIE_TEMP channels provided by PMICs. Use them to provide
temperature reading for the spmi-temp-alarm thermal zones.

[PATCH 7/7] arm64: dts: qcom: sm8450-hdk: add ADC-TM thermal zones

[Dmitry Baryshkov]

Add thermal zones controlled through the ADC-TM (ADC thermal monitoring)
PMIC interface. This includes several onboard sensors and the XO thermal
sensor.

This define should be cleaned up.. Since it takes a sid argument,
it really is ADC7_AMUX_THM1_100K_PU(sid)

I don't think I understood your comment. The define itself is specific
to PM8350, other PMICs might have different channel assignments.

Do you want to define PM8350_ADC7_AMUX_THM1_100K_PU(sid) using
ADC7_AMUX_THM1_100K_PU ?
Or to make all users use ADC7_AMUX_THM1_100K_PU? Or add the SID
argument to ADC7_AMUX_THM1_100K_PU and switch to it?

This.

Since we have a generic binding for it (not sure what sort of ABI-ish rules
apply here, probably not very many since it's just a dumb preprocessor define),
we should not redefine it for each PMIC, especially since the SIDs are variable
nowadays :/

Sorry for being too vague.

I think it would be worth to have per-PMIC headers (which define which
channels are available on this PMIC), but to use values from the
qcom,spmi-vadc.h  header to define those per-PMIC values.

WDYT?

Note that the channel relates to this PMIC, but the sid is of the
measured PMIC. So I'm not sure which PMIC you're thinking of when you
say per-PMIC...

Not quite. Both sid and channel are for the peasuring PMIC (pm8350b,
pm8350, etc). On pmk8350 we further multiplex them into the 8 channels
of adc-tm.
