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

[Boris BREZILLON]

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.

I tested it on sama5d3.
Alexandre, Jean-Jacques, could you test this series on your eval boards
(sam9261ek and sam9rlek) so that we can move to this new model and hopefully
consider the at91 clk DT binding as (almost :-)) stable.

Jean-Jacques, as you can see I reworked my first implementation as you
suggested, do you want me to add your Signed-off-by in the next version ?

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.

Best Regards,

Boris
