Public bug reported:
I'm validating latest 6.11 kernel on Qualcomm RB3Gen2
(https://www.thundercomm.com/product/qualcomm-rb3-gen-2/) and noticed
there is basically no UART output at all, even with earlycon set.
Looking at the kernel config the issue seems to be that all clocks and
uart drivers are set as module, which is loaded a bit too late in the
boot process.
