[PATCH] tty: serial: qcom-geni-serial: Drop the icc bw votes in suspend for console

When using the geni-serial as console, its important to be able to hit the lowest possible power state in suspend, even with no_console_suspend. The only thing that prevents it today on platforms like the sc7180 is the interconnect BW votes, which we certainly don't need when the system is in suspe

[RFC 3/3] cpufreq: cppc: Add support for frequency invariance

The Frequency Invariance Engine (FIE) is providing a frequency scaling correction factor that helps achieve more accurate load-tracking. Normally, this scaling factor can be obtained directly with the help of the cpufreq drivers as they know the exact frequency the hardware is running at. But that

[RFC 2/3] topology: Provide generic implementation of arch_freq_counters_available()
