Subject[PATCH] cpufreq: cpu0: make THERMAL_CPU support optional
Date
From: Rob Herring <robh@kernel.org>

The addition of THERMAL and THERMAL_CPU selections causes a kconfig
warning on highbank platforms:

warning: (ARM_HIGHBANK_CPUFREQ) selects GENERIC_CPUFREQ_CPU0 which has
unmet direct dependencies (ARCH_HAS_CPUFREQ && CPU_FREQ && HAVE_CLK &&
REGULATOR && OF && THERMAL && CPU_THERMAL)

The cpufreq-cpu0 driver does not require thermal zone support, and it
should be selectable independently. Add a new kconfig option to enable
this feature.
