…ng the kernel (latest) * arm_display: Correct logging message hdmi_pixel_freq_limit Noticed in a raspinfo log file. * Increase default v3d frqeuency on 2712d0 * pi5: arm_boot: Enable turbo clocks before loading the kernel Originally, for the entire boot ran at the idle-operating point. Subsequently, the default for intial_turbo was changed so that the kernel is started with turbo-clocks unless disabled via config.txt. This change enables the turbo-clocks as soon as it is safe as soon as the turbo voltage has been calibrated to speedup kernel loading and device-tree processing. This reduces boot time by approximately 1 second on a Pi5 booting from NVMe.
