linux-aarch64 is missing important modules for Rock5B

Please add the following modules to linux-aarch64. Rockchip devices (such as Rock5B) are missing important features due to this omission.

[code]
systemd-modules-load[418]: Failed to find module 'ledtrig-disk'
systemd-modules-load[418]: Module 'ledtrig_netdev' is built in
systemd-modules-load[418]: Failed to find module 'extcon-pd-virtual'
systemd-modules-load[418]: Failed to find module 'rockchip-cpufreq'
[/code]

The first two (ledtrid*) are builtins, no module needed. The 2nd two I cannot find in the 6.14.3 vanilla source suggesting they are out-of-tree. The linux-aarch64 package provides the vanilla kernel, you need to look for PKGBUILDs for theses and build with dkms as one option.

Are you manually defining these in a conf within /etc/modules-load.d/ ?

Indeed, some kernel config options have changed. Apparently this one is sufficient and already active:
CONFIG_DEVFREQ_EVENT_ROCKCHIP_DFI=y

Thanks, this can be closed.
