* OPP: refactor dev_pm_opp_of_register_em() and update related driversLukasz Luba2020-06-241-1/+1
| | | | | | | | | | | The Energy Model framework supports not only CPU devices. Drop the CPU specific interface with cpumask and add struct device. Add also a return value, user might use it. This new interface provides easy way to create a simple Energy Model, which then might be used by e.g. thermal subsystem.

* cpufreq: mediatek: Don't validate the frequency table twiceViresh Kumar2018-03-201-10/+1
| | | | | | | | | | | | 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.

| * cpu_cooling: Keep only one of_cpufreq*cooling_register() helperViresh Kumar2017-12-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | 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" Signed-off-by: Sean Wang <sean.wang@mediatek.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Rafael J.
