[PATCH v2 6/6] ARM: at91/dt: remove old clk material

[nicolas.ferre@atmel.com (Nicolas Ferre)]

On 11/10/2013 14:43, Boris BREZILLON :
> This patch removes the old main clk node which is now useless as sama5d3
> SoCs and boards are no longer compatible with the old at91 clk

>
> It also remove old clock definitions (clock definitions using at91 old clk

Happy to see all these lines removed!
Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com>

I am looking forward the same result on other SoCs.
