Hello Nicolas,
This patch should fix the bug you were seeing with USB device
enumaration after moving to CCF.
Tell me if this solves the issue (it worked for me).

This adds new at91 utmi clock implementation using common clk framework.
This clock is a pll with a fixed factor (x40).
It is used as a source for usb clock.

This patch adds new at91 main oscillator clock implementation using common
clk framework.
If rate is not provided during clock registration it is calculated using
the slow clock (main clk parent in this case) rate and MCFR register.

Use device tree to get the source clock of the PIT (Periodic Interval Timer).
If the clock is not found in device tree (or dt is not enabled) we'll try to
get it using clk_lookup definitions.

This patch moves at91_pmc.h header from machine specific directory
(arch/arm/mach-at91/include/mach/at91_pmc.h) to clk include directory
(include/linux/clk/at91.h).
We need this to avoid reference to machine specific headers in clk
drivers.

The clocks rate/parent change has not been tested.
