  Configure the thermals for the QUIET_THERM, CAM_FLASH_THERM, MSM_THERM
and RFC_CAM_THERM thermistors connected to PM7325.

With this PMIC the software communication to the ADC is going through
PMK7325 (= PMK8350).

(email from my other address, quicker right now)

Well yes and no.

Yes as in those are the temps specified in downstream dtb.
No as in I'm 99% sure there's user space with definitely lower threshold that 
actually does something in response to the temps.

I didn't look too much into this but does the kernel even do something when it 
hits one of these trip points? I assume when there's a cooling device thing 
specified then it can actually tell the driver to do something, but without 
(and most drivers don't support this?) I'm assuming the kernel can't do much 
anyways?

So e.g. when the temperature for the flash led is reached I'm assuming 
downstream (+Android) either dims the led or turns it off? But I'd have to dig 
quite a bit into the thermal setup there to check what it's really doing.

But for now I think it's okay to put this current thermal config into dts and 
we'll improve it later when 1. I understand more and 2. maybe some useful 
drivers support the cooling bits?

Luca

I think reaching "critical" shuts down the platform, unless something
registering the thermal zone explicitly overrides the behavior.

Yeah it's better than nothing, but ultimately we should probably move
the values that userspace daemon operates on here in the dt..

Should probably be easy to test, especially the camera flash thermal
zone heats up *very* quickly when the flash is on, so should be trivial
to set the trip point down from 125degC to e.g. 45degC and see what
happens.

So I did this and... nothing happened.
I watched /sys/class/thermal/thermal_zone34/temp climb above 45degC and
nothing happened.

I guess trip type being "passive" and no cooling-device makes it not do
anything.

  ==> /sys/class/thermal/thermal_zone34/trip_point_0_hyst <==
  1000
  ==> /sys/class/thermal/thermal_zone34/trip_point_0_temp <==
  45000
  ==> /sys/class/thermal/thermal_zone34/trip_point_0_type <==
  passive

From Documentation/devicetree/bindings/thermal/thermal-zones.yaml:

  - active   # enable active cooling e.g. fans
  - passive  # enable passive cooling e.g. throttling cpu
  - hot      # send notification to driver
  - critical # send notification to driver, trigger shutdown

So unless we want to just shut down the system (with "critical"), I
don't think thermal can't really do anything else right now, since e.g.
leds-qcom-flash.c driver doesn't have any cooling support to lower the
brightness or turn off the LED.

So.. in essence not much we can do right now.

But seems we also cannot remove this (kinda useless) trip since we need
at least one trip point in the dts if I read the bindings yaml
correctly.

For sure.. I spent a bit of time looking into the proprietary Qualcomm
thermal-daemon sources but didn't really see much interesting things
there for this platform, maybe some of this thermal handling is
somewhere else - or half of these thermal zones aren't even used with
Android.

So.. good to get the current patch upstream or not? :)

Yeah.. crashing the phone because the LED is too hot is sorta
suboptimal! Though I mainly had the skin temp in mind..

Yep, just having the ability to read out thing is always good ;)
