Hello,

This patch series is a proposal to move at91 clock implementation
to common clk framework.

Most of the clock provided by the PMC (Power Management Controller) are
implemented :
- main clock (main oscillator)
- pll clocks
- master clock
- programmable clocks
- utmi clock
- peripheral clocks
- system clocks

This implementation is compatible with device tree: the goal is
to define the whole clock tree in the device tree (all currently
available dt SoCs and boards are patched to support dt clocks).
Please feel free to comment the dt bindinds.

I removed the register_clocks function in SoC supporting dt boards only:
- at91sam9x5 SoCs
- at91sam9n12 SoC
- sama5d3 SoCs

This patch series is based on linux-next and has been tested on sama5d31ek
board using device tree. It compiles for other SoCs and both with and without
dt support, but it has not been tested.

BTW could other people test it on other boards (I only have a kizbox and
a sama5d31ek dev kit).

Best Regards,
Boris

Changes since v1:
- fix bugs in pll, programmable and system clock implementations
(wrong bit position).
- add usb clock configuration support (ohci and udc drivers +
clk_lookup for non dt boards)
- rework of the system clock interfaces (no need to define a parent clock,
system clock is a gate with no rate info)
- change system, peripheral and programmable clk dt bindings (1 master node
and multiple child nodes each defining a system/peripheral or prog clock)
- fix bugs in sama5 dt definition
