Both system clocks and EHCI subsystem, also Qualcomm power management device requires full initialization. My goal will be to extend this driver and proceed full initialization required for Qualcomm EHCI. The u-boot option CONFIG_DM_DEVICE_REMOVE=n must be added in order to keep devices initialized before jumping to FreeBSD. We will need to get rid of these by adding some code to this driver I guess.
