[PATCHv3 04/15] Thermal: Add platform level information to thermal.h

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch adds platform level information to thermal.h
by introducing two structures to hold:
 * bind parameters for a thermal zone,
 * zone level platform parameters
