    thermal: of: improve of-thermal sensor registration API · 2251aef6
    Eduardo Valentin authored
    Different drivers request API extensions in of-thermal. For this reason,
    additional callbacks are required to fit the new drivers needs.
    
    The current API implementation expects the registering sensor driver
    to provide a get_temp and get_trend callbacks as function parameters.
    As the amount of callbacks is growing, this patch changes the existing
    implementation to use a .ops field to hold all the of thermal callbacks
    to sensor drivers.
    
    This patch also changes the existing of-thermal users to fit the new
    API design. No functional change is introduced in this patch.
