[PATCH 2/7] arm64: dts: qcom: sm8250: change spmi node label

[Dmitry Baryshkov]

PMIC dtsi files (pm8150*.dtsi) expect to have spmi_bus label, rather
than just spmi. Rename spmi label accordingly.

[PATCH 5/7] arm64: dts: qcom: pm8150x: add thermal alarms and thermal zones

[Dmitry Baryshkov]

Add temperature alarm and thermal zone configuration to all three
pm8150 instances. Configuration is largely based on the msm-4.19 tree.
These alarms use main adc of the pmic. Separate temperature adc is not
supported yet.

DO you need these headers for base patch, we should add them when adding

Not sure about this, Amit..? Should this also not be in board dts?

I did look into this but the binding says,
"compatible : shall contain only one of the following"

So clearly the fallback is not going to work and there is no need to add a
dedicated compatible in the driver. The binding is not in the YAML format to
be validated but still... Other option is to convert the binding to YAML and
make the compatibles listed as 'enum' and 'const' elements appropriately.

I already converted the bindings to YAML and added the missing 
compatibles for
other SoCs[1] . I thought it was already merged since Rob has already 
reviewed
them, but seems like it was missed. Bjorn, can you please take it?

Ah, okay. I didn't find it in linux-next. Anyway, for adding
"qcom,apss-wdt-sm8250" compatible, we need to group the compatibles wisely
using 'enum' and 'const'.

I'm not so sure. This part of the configuration seems generic to me. 
Unlike adc-tm config, which definitely goes to the board file.

I can split this into a separate pm8150-temp.dtsi file. Does that sound 
better?

I think the temperature values may be board specific, Amit can confirm
that. If that is the case then this belongs to board dts, otherwise here :)

That might make it worse, we don't do splitting.

Compare this with pm8998.dtsi. It has all nodes enabled by default.

Again, pm8998 has these thermal values in the dtsi file. In V2 I will
update these three files to follow pm8998.dtsi.

Is the default disabled for a reason?

I'd expect the default to be enabled and then board-specific dts to
disable a specific adc if needed.

Since there is not cooling map associated with these two trips i.e. no
mitigation action, this trip is informational. So make it of type
"hot".

Is there really a need for two passive trip points? Just one at 115
should be enough?

Are you sure about this? That is a very toasty temperature. :-)

The last trip should typically be of type "critical". That is the
temperature at which the system will initiate a shutdown.

While the temp values can be board-specific e.g. if the same SoC is
used in a mobile phone and a laptop, the thresholds rarely change, in
my experience.

I think they can stay in the pmic dtsi file and any specific board can
override if necessary.

Right, let's not split it.

This is unnecessary. I've already started preparing patches that add
the thermal zones for the two socs.

Please name this "pon", just for consistency.

Can you confirm that pm8009 is subtype 1, and hence the reboot reason
going into RB_SPARE should be shifted 2 steps, rather than 1 as in the
newer PMICs?

Would be nice if we had a generic compatible that read the subtype,
rather than having to add new compatibles for each pmic (or use the old
ones)...

Bjorn

For pm8009 the subtype reads as 0x07, while according to msm-4.19 gen2
handling is only enabled for subtypes 0x04 and 0x05.

Will do it in a separate patch.
