Axel Lin f534e9bf80 thermal: db8500: Fix checking return value of thermal_zone_device_register
thermal_zone_device_register() returns ERR_PTR on error, thus use
IS_ERR rather than IS_ERR_OR_NULL to check return value.

Sachin Kamat c313637641 thermal: db8500: Use of_match_ptr() macro in db8500_thermal.c
This eliminates having an #ifdef returning NULL for the case
when OF is disabled.

hongbo.zhang aa1acb0451 Thermal: Add ST-Ericsson DB8500 thermal driver.
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.
