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.

Changes in v2:
- fix build error for sam9x60_curiosity_mmc1_defconfig
- took over the upstream process from Sergiu

Claudiu Beznea (1):
  clk: at91: pmc: export clock setup to pmc

Sergiu Moga (4):
  clk: at91: Add support for sam9x60 USB clock
  clk: at91: sam9x60: Register the required clocks for USB
  clk: at91: sam9x60: Add initial setup of UPLL and USBCK rates
  configs: at91: sam9x60: Add required configs for the USB clock
