cpufreq_cooling_register() expects mask of all the CPUs where frequency
constraint is applicable.This platform has more than one CPU to which these constraints will apply and so
passing mask of only CPU0 wouldn't be sufficient. Also, this platform has a
single cluster of CPUs and the constraint applies to all CPUs.If CPU0 is hoplugged out then we may face strange BUGs as cpu_cooling framework
isn't aware of any siblings sharing clock line.Fix it by passing cpu_present_mask to cpufreq_cooling_register().

In this patch, the cpu_cooling code checks for the usability of cpufreq
layer before proceeding with the CPU cooling device registration. The
main reason is: CPU cooling device is not usable if cpufreq cannot
switch frequencies.Similar checks are spread in thermal drivers. Thus, the advantage now
is to have the check in a single place: cpu cooling device registration.
For this reason, this patch also updates the existing drivers that
depend on CPU cooling to simply propagate the error code of the cpu
cooling registration call. Therefore, in case cpufreq is not ready, the
thermal drivers will still return -EPROBE_DEFER, in an attempt to try
again when cpufreq layer gets ready.Cc: devicetree@vger.kernel.org

This patch changes the driver to avoid the usage of IS_ERR_OR_NULL()
macro. This macro can lead to dangerous results, like returning
success (0) during a failure scenario (NULL pointer handling).The case present in this driver can be translated to a simple
check for IS_ERR(), as the cpufreq_cooling_register() returns
either a valid pointer or an ERR_PTR().Cc: Zhang Rui

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.Signed-off-by: hongbo.zhang
