Amit Kucheria 0db60d6b89 cpufreq: mediatek: Use auto-registration of thermal cooling device
Use the CPUFREQ_IS_COOLING_DEV flag to allow cpufreq core to
automatically register as a thermal cooling device.

This allows removal of boiler plate code from the driver.

Viresh Kumar b563afbaa8 cpufreq: mediatek: Don't validate the frequency table twice
The cpufreq core is already validating the CPU frequency table after
calling the ->init() callback of the cpufreq drivers and the drivers
don't need to do the same anymore. Though they need to set the
policy->freq_table field directly from the ->init() callback now.

Stop validating the frequency table from mediatek driver.

Viresh Kumar 3ebb62ffc4 cpu_cooling: Keep only one of_cpufreq*cooling_register() helper
of_cpufreq_cooling_register() isn't used by anyone and so can be
removed, but then we would be left with two routines:
cpufreq_cooling_register() and of_cpufreq_power_cooling_register() that
would look odd.

Remove current implementation of of_cpufreq_cooling_register() and
rename of_cpufreq_power_cooling_register() as
of_cpufreq_cooling_register(). This simplifies lots of stuff.

Viresh Kumar f5f263fed6 cpu_cooling: Make of_cpufreq_power_cooling_register() parse DT
All the callers of of_cpufreq_power_cooling_register() have almost
identical code and it makes more sense to move that code into the helper
as its all about reading DT properties.

This got rid of lot of redundant code.

Jesse Chan 7e8a09e05a cpufreq: mediatek: add missing MODULE_DESCRIPTION/AUTHOR/LICENSE
This change resolves a new compile-time warning
when built as a loadable module:

WARNING: modpost: missing MODULE_LICENSE() in drivers/cpufreq/mediatek-cpufreq.o
see include/linux/module.h for more information

This adds the license as "GPL v2", which matches the header of the file.

MODULE_DESCRIPTION and MODULE_AUTHOR are also added.

MT7622 is a 64-bit ARMv8 based dual-core SoC (2 * Cortex-A53) with a
single cluster. The hardware is also compatible with the current driver,
so add MT7622 as one of the compatible string list.

Sean Wang 862e0104f4 cpufreq: mediatek: add cleanups with the more generic naming
Since more MediaTek SoCs can be supported with the cpufreq driver and not
limited to MT8173, a couple of cleanups are done here with renaming those
functions and related structures with "mtk" instead of "mt8173".

MT2701/MT7623 is a 32-bit ARMv7 based quad-core (4 * Cortex-A7) with
single cluster and this hardware is also compatible with the existing
driver through enabling CPU frequency feature with operating-points-v2
bindings. Also, this driver actually supports all MediaTek SoCs, the
Kconfig menu entry and file name itself should be updated with more
generic name to drop "MT8173"
