[PATCH] clk: imx25: set correct parents for ssi ipg clocks

[Martin Kaiser]

The ssi1_ipg clock depends on ssi1_ipg_per. Set ssi1_ipg_per as parent
clock of ssi1_ipg. Without this link, the fsl_ssi driver does not
activate the ssi1_ipg clock correctly and ssi1 is unable to transfer
audio data.

Fix the parent clock of ssi2 as well, it shows the same behaviour.

Dear all,

could you have a look at this patch? This makes SSI1 and 2 work for me.
With the default "ipg" parent clocks, I get no ipg clocks on the SSIs.
However, I was wondering why we don't need anything similar e.g. for the
UARTs...

Best regards,
Martin
