The crypto SRAM, used by the armada 370 cpuidle code to workaround a bug
in the BootROM code, requires the crypto clk to be up and running.
Flag the crypto clk as IGNORE_UNUSED until we add the proper
infrastructure to define the crypto SRAM in the DT and reference the crypto
clk in this SRAM node.

Would it possible to apply this fix on 4.1-rc8 ?

Hi Gregory,

I'm a bit confused by this. This patch fixes "clk: mvebu: add missing
CESA gate clk", right? That patch lives in clk-next. It was not pushed
to Linus' tree yet via a -fixes branch.

Thus I can just apply this patch to clk-next and the problem should be
resolved in clk-next, no?

Furthermore, I do not have 29e623475c50267ee3aaa49ebb6cbe107bce8d2a
anywhere in my tree. I'm not sure where this sha1 hash came from.

Regards,
Mike

Thanks,

Gregory
