Merge tag 'cpufreq-arm-updates-6.11' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/vireshk/pm

Merge ARM cpufreq updates for 6.11 from Viresh Kumar:

"- cpufreq: Add Loongson-3 CPUFreq driver support (Huacai Chen).
 - Make exit() callback return void (Lizhe and Viresh Kumar).
 - Minor cleanups and fixes in several drivers (Bryan Brattlof,
   Javier Carrasco, Jagadeesh Kona, Jeff Johnson, Nícolas F. R. A. Prado,
   Primoz Fiser, Raphael Gallais-Pou, and Riwen Lu)."
