devicetree node for i.MX51 CPUs.

Is it correct?  I think there should be a physical clock for weim.

Yes, but properly clock for weim is missing in the clk subsystem,
so I think at this point it is OK. Adding a properly clock should be a separate patch.
Thanks.

I've seen emi_slow and emi_fast clocks implemented in clk-imx51-imx53.c.
Neither is the clock for weim?

I reviewed the documentation, emi_fast clock is used for DDR, emi_slow for WEIM,
so will post the revised patch.
Thanks.
