This driver is based on the thermal management framework in thermal_sys.c. A thermal zone device is created with the trip points to which cooling devices can be bound, the current cooling device is cpufreq, e.g. CPU frequency is clipped down to cool the CPU, and other cooling devices can be added and bound to the trip points dynamically. The platform specific PRCMU interrupts are used to active thermal update when trip points are reached.

Shouldn't it depend on THERMAL as well, as in Hongbo's original patch?
all of these options are available only if CONFIG_THERMAL is set. please refer to commit 72e198978223f2020f7f59a6e2520f2b7d005e72 in the thermal next tree.

Adds DB8500 thermal management implementation according to the thermalmanagement framework. A thermal zone with several trip points will becreated. Cooling devices can be bound to the trip points to cool thisthermal zone if trip points reached.+config DB8500_CPUFREQ_COOLING

Adds DB8500 cpufreq cooling devices, and these cooling devices can bebound to thermal zone trip points. When a trip point reached, thebound cpufreq cooling device turns active to set CPU frequency low tocool down the CPU.endif
