[PATCH v2 00/11] ARM: at91: rework main and slow clk implementation

Hello,

This series introduce the real clock model (as described in atmel datasheets)
for slow and main clocks.

The modifications introduced by this series break the DT compat, but, as the
at91 CCF based implementation is pretty new (introduced in 3.14 only for sama5
eval boards) I think it won't impact a lot of users.

Nicolas, Mike, if this series is accepted, I'd like to get it merged as soon as
possible to prevent other developpers from using a deprecated DT binding.
Moreover, I think this series should go through the same path for both clk
and DT changes (whatever path is chosen: either at91 or clk tree) because the
changes are tightly coupled.

Best Regards,

Boris

- fix sam9rl main clk definition
