Is is (more or less) in line with the other imx functions that
dynamically add platform devices.

I consider it OK for now.  I know Eric does/wants something similar for
pxa.  If you want to push forward unification here that's great, but
IMHO this is nothing that should stop this patch which is a good step
forward.

BTW another low hanging fruit is to use use
platform_device_register_resndata to implement imx_add_platform_device
and add a few additional checks, like warn if CONFIG_DEBUG_SOMETHING is
enabled and data is non-NULL and doesn't point to .init-memory.)

Best regards
Uwe
