[PATCH 0/5] Support the required clocks to enable USB on SAM9X60

[Sergiu Moga]

This patch series originates from a bigger patch series:
https://lists.denx.de/pipermail/u-boot/2022-December/502865.html

A driver for clock operations on SAM9X60's USB clock has been added as
well as its registration on CCF. In order for USB to work properly, the
UPLL and USBCK need an initial frequency before probing the OHCI/EHCI
driver. Furthermore enable this driver in the defconfigs.
