[PATCH 1/2] thermal/drivers/iwlwifi: Use generic thermal_zone_get_trip() function

[Daniel Lezcano]

The thermal framework gives the possibility to register the trip
points with the thermal zone. When that is done, no get_trip_* ops are
needed and they can be removed.

The get_trip_temp, get_trip_hyst and get_trip_type are handled by the
get_trip_point().

The set_trip_temp() generic function does some checks which are no
longer needed in the set_trip_point() ops.

Convert ops content logic into generic trip points and register them
with the thermal zone.

The subject should begin with "wifi: iwlwifi: ".

I don't see patch 2. Via which tree is the plan for this patch?

Gregory, please review this.

patch 2 are similar changes but related to the mellanox driver.

This is the continuation of the trip point rework:

https://lore.kernel.org/netdev/20221003092602.1323944-22-daniel.lezcano@linaro.org/t/

This patch is planned to go through the thermal tree

Sorry I should have mentioned that.

Vadim, can you please review and test?

Daniel, I saw that you wrote to Kalle that you want to take it via the
thermal tree. Any reason not to take it via net-next? I'm asking because
it will be the second release in a row where we need to try to avoid
conflicts in this file.

Thanks

As Kalle commented above, the subject should start with wifi: iwlwifi:
The commit itself seems fine to me.

Ok, feel free to take this via the thermal tree:

Because I hope I can remove the ops->get_trip_ ops from thermal_ops 
structure before the end of this cycle.

May be you can consider moving the thermal driver into drivers/thermal?

OK. Vadim, any chance you can review the patch?

> May be you can consider moving the thermal driver into drivers/thermal?

I don't think it's worth the hassle (if possible at all). In practice,
this code is upstream for almost six years and IIRC we didn't have any
conflicts with the thermal tree. I don't expect conflicts this cycle
either.

It seems to be OK.
Anyway, I'll take this patch for testing by the end of this week and update.

Hi guys,

I see this patch is already applied to Linux-next.
I tested it along with relevant patches from drivers/thermal and it looks OK.

Thanks,
Vadim.
