Fwiw, even without this patch they're picked up by cpufreq-dt for me: user@trixie:~$ sudo cpupower frequency-info analyzing CPU 5: driver: cpufreq-dt CPUs which run at the same hardware frequency: 4 5 6 7 CPUs which need to have their frequency coordinated by software: 4 5 6 7 maximum transition latency: 40.0 us hardware limits: 408 MHz - 2.30 GHz available frequency steps: 408 MHz, 600 MHz, 816 MHz, 1.01 GHz, 1.20 GHz, 1.42 GHz, 1.61 GHz, 1.80 GHz, 2.02 GHz, 2.21 GHz, 2.30 GHz available cpufreq governors: ondemand userspace performance schedutil current policy: frequency should be within 408 MHz and 2.30 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: 1.61 GHz (asserted by call to hardware) user@trixie:~$ uname -a Linux trixie 6.15.0-11173-g546b1c9e93c2 #2 SMP PREEMPT Wed Jun 4 20:32:52 CEST 2025 aarch64 GNU/Linux this is more correct though of course.
