      MAINTAINERS: add thermal bindings entry in thermal domain · 1beabfbe
      Eduardo Valentin authored
      After discussion and agreement of thermal device tree bindings,
      it is desirable to properly maintain thermal bindings for
      existing and upcoming devices.
      
      As original author of thermal device tree bindings, I am
      volunteering to maintain them. This then adds and entry
      for device tree bindings under thermal domain.

      thermal: ti-soc-thermal: use thermal DT infrastructure · 26d9cc65
      Eduardo Valentin authored
      This patch improves the ti-soc-thermal driver by adding the
      support to build the thermal zones based on DT nodes.
      
      The driver will have two options now to build the thermal
      zones. The first option is the zones originally coded
      in this driver. So, the driver behavior will be same
      if there is no DT node describing the zones. The second
      option, when it is found a DT node with thermal data,
      will used the common infrastructure to build the thermal
      zone and bind its cooling devices.
      
      In case the driver loads thermal data using the legacy
      mode, this driver still adds to the system
      a cpufreq cooling device. Loading the thermal data from
      DT, the driver assumes someone else will add the cpufreq
      cooling device, like the cpufreq driver.

      cpufreq: cpufreq-cpu0: add dt node parsing for cooling device properties · 77cff592
      Eduardo Valentin authored
      This patch changes the cpufreq-cpu0 driver to consider if
      a cpu needs cooling (with cpufreq). In case the cooling is needed,
      the cpu0 device tree node needs to be properly configured
      with cooling device properties.
      
      In case these properties are present,, the driver will
      load a cpufreq cooling device in the system. The cpufreq-cpu0
      driver is not interested in determining how the system should
      be using the cooling device. The driver is responsible
      only of loading the cooling device.
      
      Describing how the cooling device will be used can be
      accomplished by setting up a thermal zone that references
      and is composed by the cpufreq cooling device.

      thermal: introduce device tree parser · 4e5e4705
      Eduardo Valentin authored
      This patch introduces a device tree bindings for
      describing the hardware thermal behavior and limits.
      Also a parser to read and interpret the data and feed
      it in the thermal framework is presented.
      
      This patch introduces a thermal data parser for device
      tree. The parsed data is used to build thermal zones
      and thermal binding parameters. The output data
      can then be used to deploy thermal policies.
      
      This patch adds also documentation regarding this
      API and how to define tree nodes to use
      this infrastructure.
      
      Note that, in order to be able to have control
      on the sensor registration on the DT thermal zone,
      it was required to allow changing the thermal zone
      .get_temp callback. For this reason, this patch
      also removes the 'const' modifier from the .ops
      field of thermal zone devices.

      thermal: allow registering without .get_temp · 81bd4e1c
      Eduardo Valentin authored
      This patch changes the thermal core driver to allow
      registration of thermal zones without the .get_temp callback.
      
      The idea behind this change is to allow lazy registration
      of sensor callbacks.
      
      The thermal zone will be disabled whenever the ops
      does not contain a .get_temp callback. The sysfs interface
      will be returning -EINVAL on any temperature read operation.
