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
