The sama5d2 requires the clock provider initialized before timers.
We can't use a platform driver for the sama5d2-pmc driver, as the
platform_bus_init() is called later on, after time_init().
As fw_devlink considers only devices, it does not know that the
pmc is ready. Hence probing of devices that depend on it fail:
probe deferral - supplier f0014000.pmc not ready
Fix this by setting the OF_POPULATED flag for the sama5d2_pmc
device node after successful setup. This will make
of_link_to_phandle() ignore the sama5d2_pmc device node as a
dependency, and consumer devices will be probed again.

I'll be out of office, will check the rest of the at91 SoCs
at the begining of next week.
