>>> If I called imx_cpuidle_init directly from imx5 or imx6q init

>>> One alternative would be to add a function to return the pointer to

>>> use that machine based method without adding that extra code.
>>> Another alternative would be to add a general platform lateinit_call
>>> function to each platforms that support cpuidle.
>> Just put the initcall into mm-imx5.c and check the cpu type. Then you

> That solution is currently available for imx5 but for imx6q it implies
> adding the cpu type support for imx6q.  Are you ok with that?

Sascha or Shawn, any further comments on my question?
