Subject: [PATCH 00/15] thermal OF rework
Date: Wed, 27 Apr 2022 00:15:08 +0200 [thread overview]
Message-ID: <20220426221523.3056696-1-daniel.lezcano@linexp.org> (raw)
The thermal framework initialization with the device tree appears to
be complicated and hard to make it to evolve.
It contains duplication of almost the same thermal generic structures
and has an assymetric initialization making hard any kind of serious
changes for more complex features. One of them is the multiple sensors
support per thermal zone.
In order to set the scene for the aforementioned feature with generic
code, we need to cleanup and rework the device tree initialization.
However this rework is not obvious because of the multiple components
entering in the composition of a thermal zone and being initialized at
different moments. For instance, a cooling device can be initialized
before a sensor, so the thermal zones must exist before the cooling
device as well as the sensor. This asynchonous initialization forces
the thermal zone to be created with fake ops because they are
mandotory and build a list of cooling devices which is used to lookup
afterwards when the cooling device driver is registering itself.
Actually, the correct behavior IMHO, would be having a sensor
registration resulting in the thermal zone creation. If the cooling
device is registered before, it won't find the thermal zone and should
return -EPROBE_DEFER.
As there could be a large number of changes, this first series provide
some steps forward for a simpler device tree initialization.
The first patch could appear scary as it touches a big number of files
but it is actually just renaming a structure name
Daniel Lezcano (15):
thermal/core: Rename thermal_zone_device to thermal_zone
thermal/core: Change thermal_zone_ops to thermal_sensor_ops
thermal/core: Add a thermal sensor structure in the thermal zone
thermal/core: Remove duplicate information when an error occurs
thermal/of: Replace device node match with device node search
thermal/of: Remove the device node pointer for thermal_trip
thermal/of: Move thermal_trip structure to thermal.h
thermal/core: Remove unneeded EXPORT_SYMBOLS
thermal/core: Move thermal_set_delay_jiffies to static
thermal/core: Rename trips to ntrips
thermal/core: Add thermal_trip in thermal_zone
thermal/core: Register with the trip points
thermal/of: Store the trips in the thermal zone
thermal/of: Use thermal trips stored in the thermal zone
thermal/of: Initialize trip points separately
