[PATCH 0/4] arm64: dts: qcom: sc7180: Disable the charger thermal zone on more trogdor boards

[PATCH 0/4] arm64: dts: qcom: sc7180: Disable the charger thermal zone on more trogdor boards

[Matthias Kaehlcke]

We already disabled the charger thermal zone for lazor to avoid
bogus temperature readings from an unsupported thermistor. Some
revisions of other trogdor boards that are added by Doug's
'arm64: dts: qcom: Update sc7180-trogdor variants from downstream'
series have the same problem. Disable the charger thermal zone for
them too.

This series is based on v2 of the 'arm64: dts: qcom: Update
sc7180-trogdor variants from downstream' series
(https://patchwork.kernel.org/project/linux-arm-msm/list/?series=440315)

[PATCH 1/4] arm64: dts: qcom: sc7180: lazor: Simplify disabling of charger thermal zone

[Matthias Kaehlcke]

Commit f73558cc83d1 ("arm64: dts: qcom: sc7180: Disable charger
thermal zone for lazor") disables the charger thermal zone for
specific lazor revisions due to an unsupported thermistor type.
The initial idea was to disable the thermal zone for older
revisions and leave it enabled for newer ones that use a
supported thermistor. Finally the thermistor won't be changed
on newer revisions, hence the thermal zone should be disabled
for all lazor (and limozeen) revisions. Instead of disabling
it per revision do it once in the shared .dtsi for lazor.

[PATCH 2/4] arm64: dts: qcom: sc7180: Add pompom rev3

[Matthias Kaehlcke]

The only kernel visible change with respect to rev2 is that pompom
rev3 changed the charger thermistor from a 47k to a 100k NTC to use
a thermistor which is supported by the PM6150 ADC driver.

[PATCH 3/4] arm64: dts: qcom: sc7180: pompom: Disable charger thermal zone for rev1 and rev2

Pompom rev1 and rev2 are stuffed with a 47k NTC as thermistor for the
charger temperature which currently isn't supported by the PM6150 ADC

The idea is right, but I'm having a hard time figuring out what tree
you posted your patch against. You said you did it atop my "v2" series
[1], right?  ...but the "sc7180-trogdor-lazor.dtsi" really doesn't
match. In my tree, for instance, right above the PINCTRL comment
should be:

&wifi {
  qcom,ath10k-calibration-variant = "GO_LAZOR";
};

...but that's definitely not what's there in whatever your patch was
written against... It seems like you're also missing the panel and
trackpad nodes...

I don't love copying all this keymap stuff.  Options I can think of:

1. Just put it in "-rev3".  Have the "-rev2" dts just include the
"-rev3" dts and then override the model/compatible and disable the
charger_thermal.

2. Put the keyboard stuff in the "dtsi" file and then "-rev1" can have
something like:

/delete-node/ keyboard_controller;
#include <arm/cros-ec-keyboard.dtsi>

In general the preference is that the ugly device trees should get
pushed down to earlier revs since (eventually) they can just be
dropped.

I'll also mention that I don't see a huge benefit in this being a
separate patch from the next one--I'd just squash them together...

I guess this patch is written with the assumption that eventually
we'll create a "-r3" or "-r4" that has a proper thermistor stuffed but
maybe we're not sure which one?  Right now you're disabling it for
both -r1 and -r2+ which is all revisions, so this could go in the
coachz.dtsi file...

You got me! I was too lazy to pick all 13 patches, since most of them are
irrelevant for this series, but apparently I missed some that are. I guess
I'll pick them all for v2 ...

Thanks, I'll evaluate the options you suggested.

It keeps the individual patches simpler by doing one thing at a time,
but you can certainly go either way.

The proper thermistor should be stuffed in rev3.

For some reason there was already a -r3 .dts in my mental model,
probably I created one when I started with a downstream version of
this series just before you posted your's to bring upstream (mostly)
in sync with downstream. I'll add it in v2.
