[PATCH v2 0/6] thermal: tegra: soctherm bugfixes

[PATCH v2 0/6] thermal: tegra: soctherm bugfixes

[Nicolas Chauvet]

When using tegra_soctherm driver on jetson-tk1, the following messages
can be seen:
from kernel: tegra_soctherm 700e2000.thermal-sensor:
 throttle-cfg: heavy: no throt prop or invalid prop
 soctherm: trip temperature -2147483647 forced to -127000
 thermtrip: will shut down when cpu reaches 101000 mC
 soctherm: trip temperature -2147483647 forced to -127000
 thermtrip: will shut down when gpu reaches 101000 mC
 soctherm: trip temperature -2147483647 forced to -127000
 thermtrip: will shut down when pll reaches 103000 mC
 throttrip: pll: missing hot temperature
 soctherm: trip temperature -2147483647 forced to -127000
 thermtrip: will shut down when mem reaches 101000 mC
 throttrip: mem: missing hot temperature
 IRQ index 1 not found

This serie fixes two errors and two warnings that are reported in dmesg
It was compiled and tested at runtime on jetson-tk1 only.


v2:
 * Add missing tegra210 device-tree properties
 * Add the appropriate prefix for tegra soctherm
 * Use SoCs condition over of_compatible

[PATCH v2 6/6] thermal: tegra: Avoid setting edp_irq when not relevant

[Nicolas Chauvet]

According to the binding, the edp_irq is not available on tegra124/132

This commit moves the initialization of tegra->edp_irq after the
introduced has_edp_irq condition. This will have the following effects:
 - soctherm_interrupts_init will not return prematurely with unfinished
thermal_irq initialization on tegra124 and tegra132
 - edp_irq initialization will be done only when relevant

As a result, this will clear the following error on jetson-tk1 :
  kernel: tegra_soctherm 700e2000.thermal-sensor: IRQ index 1 not found

v2:
    * Use .has_edp_irq boolean instead of of_compatible
    * Switch subject prefix to use thermal instead of ARM

Fixes: 4a04beb1bf2e (thermal: tegra: add support for EDP IRQ)

It appears that the binding doc is not update to date or missing the
relevant information. Looking at the Tegra124 TRM I see that there is a
SOCTHERM EDP IRQ (51) and so maybe the correct fix is to add this.

Cheers
Jon

Hello,
This series is still pending review.

Thierry, do you expect some reviewers from the linux-pm (Zhang, Daniel ?)
To me it seems like tegra specific changes, so maybe a Nvidia reviewer
is awaited ?

Thanks.

I can apply the patch 6/6, other patches must go through arm-soc tree.

Thierry can you give your blessing ?

Thanks

As Jon mentioned, making support for that EDP IRQ doesn't seem to be the
right thing. If this IRQ does exist on Tegra124/Tegra132, then a more
correct patch would be to add that to the device tree. I vaguely recall
writing a patch to do that, a while back when I was trying to get rid of
a couple of dt_binding_check warnings/errors, so I'll dig around for
that.

I think for now we should probably ignore the driver patch. I'll get
back to you if we determine that EDP IRQ is not present on those SoCs,
in which case the driver patch would be correct.

I've applied all these...

and sent out a couple of patches that should make this obsolete since
the EDP IRQ does exist on Tegra124/Tegra132 according to the TRM.
