Subject: [PATCH v4 00/30] Rework the trip points creation
This work is the pre-requisite of handling correctly when the trip
point are crossed. For that we need to rework how the trip points are
declared and assigned to a thermal zone.
Even if it appears to be a common sense to have the trip points being
ordered, this no guarantee neither documentation telling that is the
case.
One solution could have been to create an ordered array of trips built
when registering the thermal zone by calling the different get_trip*
ops. However those ops receive a thermal zone pointer which is not
known as it is in the process of creating it.
This cyclic dependency shows we have to rework how we manage the trip
points.
Actually, all the trip points definition can be common to the backend
sensor drivers and we can factor out the thermal trip structure in all
of them.
Then, as we register the thermal trips array, they will be available
in the thermal zone structure and a core function can return the trip
given its id.
The get_trip_* ops won't be needed anymore and could be removed. The
resulting code will be another step forward to a self encapsulated
generic thermal framework.
Most of the drivers can be converted more or less easily. This series
does a first round with most of the drivers. Some remain and will be
converted but with a smaller set of changes as the conversion is a bit
more complex.
Changelog:
v4:
- Remove extra lines on exynos changes as reported by Krzysztof Kozlowski
- Collected tags
v3:
- Reorg the series to be git-bisect safe
- Added the set_trip generic function
- Added the get_crit_temp generic function
- Removed more dead code in the thermal-of
- Fixed the exynos changelog
- Fixed the error check for the exynos drivers
- Collected tags
v2:
- Added missing EXPORT_SYMBOL_GPL() for thermal_zone_get_trip()
- Removed tab whitespace in the acerhdf driver
- Collected tags
